How to Train for Hypertrophy: The Smart Way to Build Muscle Fast

Building muscle is something that’s confused scientists and gym-goers alike for decades. How do we actually get our muscles to grow? These days, with fitness advice flying at us from every direction – influencers, TikTok ‘experts’, and your mate’s dodgy training plans – it’s harder than ever to know exactly what we should be doing and who to trust.

This guide aims to cut through the noise and give you a clear, research-backed roadmap for muscle growth. We’ll focus on the best ways to trigger and optimise hypertrophy, the key principles behind it, common mistakes to avoid, and answer some frequently asked questions along the way. Enjoy.

The Process of Muscle Hypertrophy 🧠

Muscle hypertrophy is the science term for muscle growth – literally making your muscles bigger and stronger. But how does that actually happen? Hypertrophy is typically achieved through resistance training, and occurs when muscles are exposed to enough tension and workload to stimulate growth. Here is how the process works:

Your muscles are challenged: When you lift weights, do bodyweight exercises or any sort of resistance training at all, you’re putting your muscles under more stress than they’re used to. This creates tiny tears in your muscle fibres. While this sounds counterproductive, this is what we want to happen.
Your body repairs and reinforces: After your workout, your body starts repairing those tiny tears. It builds them back stronger and slightly bigger to prepare for the next time they are under stress.
Recovery: To rebuild muscle, your body needs protein (from food) and rest (from sleep and recovery days). Without those, hypertrophy will not happen to any significant amount.
Repeat: Repeating this cycle over and over will cause your muscles to grow bigger and bigger. This process can be optimised using the key principles of hypertrophy, which we break down in the next section.

Muscle hypertrophy isn’t magic, it’s a repeatable process that happens when you give your body the right signal (training) and the right resources (food + rest).

The Key Principles of Training for Muscle Growth ➡️

To maximise hypertrophy, there are several non-negotiable principles that you need to follow. These aren’t just ‘nice to have’, they are the ingredients for consistent, noticeable muscle growth. We’ve broken them down into three key areas: fundamentals, routine optimisation, and recovery.

Fundamentals for Effective Hypertrophy Training

The essentials to keep in mind every time you train, no matter your programme.

Consistency

Muscle growth demands repetition and consistent training.

Train regularly: Aim for 3-5 sessions per week, every week. It’s much better to hit 3 workouts consistently than 5 workouts one week and only one the next. Pick a schedule you can stick to! And remember, inconsistent training leads to inconsistent results.
Stick to a programme: Don’t flip-flop between different training plans every other week just because something flashy pops up on your feed. Stick to a consistent workout split for a significant period – 12 weeks or more. This makes it so much easier to accurately track progress and actually see the results of your current programme before moving on to something new.
Intensity matters: Put effort and intent into every session. If your energy is low, consider why. Are you well recovering properly? What is your pre-workout routine? Are you training at the best time of the day for you? Find what works and stick to it. Half-hearted workouts won’t get you far, but just showing up beats not showing up at all.

Progressive Overload

To keep growing, your muscles require progressively more challenge. Your body won’t adapt unless you give it a reason to. Progressive overload is about gradually increasing the demand on your muscles over time.

Progress on purpose: You need to apply more stimulus to your muscles over time, otherwise they have no reason to grow any bigger. If your goal is to build muscle, progressive overload should be a priority, and this should also align with your diet.
Methods of progressive overload:
- Increase repetitions using the same weight.
- Add weight once you hit your target rep range.
- Improve form and range of motion. This can include focusing on mind-muscle connection, slowing down the eccentric (lowering) phase of the movement, and really feeling the squeeze and stretch.
Combine methods: There is only so much you can improve your form, so combining this with another method of progressive overload is essential for consistent progress.
Track progress: Tracking your progress makes it much easier to progressively overload as you have a set target to aim for and surpass. Guessing which weight you should use leads to wasted sets when you realise you could’ve gone heaver or done more. Beginners and casual lifters should aim to track their main compound lifts (usually the first 1 or 2 exercises at the start of a session). Intermediate and advanced lifters should aim to track both their main lifts and regular accessory lifts.

Muscle Tension

Keeping the muscle under constant, controlled tension during each rep is one of the most effective habits for building size.

Move with control: Don’t rush through your sets. Focus on slow, deliberate reps, especially during the eccentric (lowering) phase. This increases time under tension – a key driver of muscle growth. The tempo of a lift refers to how fast or slow you perform the concentric (raising) and the eccentric (lowering) phase of the movement, as well as how long you pause at the top or bottom of the rep. We cover exact tempo recommendations to optimise each rep further down.
Use a full range of motion: Each rep should take the muscle through a full, safe stretch and contraction. This activates more muscle fibres and supports better gains compared to half-reps.
Avoid ‘dead zones’ in your lifts: Try not to rest in positions where the muscle relaxes – like locking out at the top of a bench press. Staying under tension keeps the muscle working, boosts overall time under tension, and makes every rep more effective.
Listen to your body: Some exercises will just feel better for you than others. Start with the basics and as you gain experience, notice which movements feel like they hit the target muscle best. Over time, you can tailor your routine to those lifts.

Once you’re comfortable with the basic rules above, it’s time to break them. More advanced lifters can incorporate techniques such as ‘cheat’ reps, partial reps or rest-pause sets into their routine. These are all ways to push the target muscle to and past failure. Best utilised sparingly, safely, and ideally with a spotter when needed.

How to Optimise Your Workout Routine for Hypertrophy

Once you’ve got your training principles down, it’s time to optimise your routine for consistent, long-term growth. This is where principles like volume, rep ranges, and rest periods all come into play.

Volume

Volume refers to your total number of working sets per muscle group, per week, and it’s one of the biggest drivers of muscle growth.

Optimise your volume: For most lifters, the sweet spot is 12–20 sets per muscle group per week.
- Go too low, and you risk not stimulating the muscle enough to grow.
- Go too high, and you face diminishing returns, where added volume leads to little extra growth but ramps up fatigue, increases injury risk, and becomes tough to recover from.
Spread your sets across the week: Instead of cramming 16 sets of chest into one brutal session, split them into two more manageable sessions, for example, 8 sets on Monday and 8 on Thursday. This helps manage fatigue, improves performance, and still delivers the same total volume. This way of training also gives your muscles multiple growth signals throughout the week. So rather than blasting chest once and waiting a full week to train it again, the stimulus is consistent which leads to better growth over time.
Start with what you can recover from:
- Beginners: Start at 12–14 sets/week and increase slowly as you adapt.
- Advanced lifters: May benefit from 16–20 sets/week, and maybe even a little more, but only if recovery, nutrition, and sleep are optimal.

Muscles grow when you recover, not when you train, so try and avoid hitting the same muscle group on consecutive days. Ideally, train each muscle group 2–3 times per week, spaced out across the week.

Reps, Sets & Tempo

How you perform your sets matters just as much as how many you do. Controlled reps, appropriate rest, and smart tempo choices all help maximise the muscle-building effect of your training.

Optimal rep ranges: The truth is, you can build muscle with most sensible rep ranges if you know what you’re doing, but this doesn’t mean all rep ranges are practical or sustainable. Stick to 6–12 reps per set if you have hypertrophy in mind. This range offers the best balance of time under tension while not overly stressing joints or having endurance as a limiting factor.
Tempo matters: Each rep should be controlled and deliberate – try to get out of the habit of moving the weight from A to B mindlessly.
- Eccentric (lowering) phase: Take 2–4 seconds to maximise control, time under tension and muscle fibre recruitment.
- Concentric (lifting) phase: Aim for a strong, clean and controlled contraction – 1-2 seconds.
- Pause: Take a 1 second pause in the stretched position. A squeeze in the contracted position is fine, but try not to rest when the muscle is not under tension.

Use a full range of motion: Where safe and possible, aim to stretch and contract the muscle through its full range. This increases muscle fibre activation and improves long-term mobility and stability. Don’t bounce, rush, or cheat the movement – let the muscle do the work.

How to Recover for Hypertophy

There are two main types of recovery in training: between-set recovery (the rest you take between sets), and between-session recovery (the rest days you take between workouts to allow muscles to repair and grow).

Between-set Recovery for hypertrophy: How long should you rest between sets?

Optimising your rest time between sets is never going to be the biggest driver of hypertrophy, but it will help with consistency and progress so you can get the most out of your training.

The issue with not resting for long enough: Pretty much common sense – if you don’t rest for long enough, your muscles won’t recover enough for the next set. You’ll likely struggle to hit your target rep-range or have to drop the weight, leading to reduced training volume over time.
This issue with resting for too long: Less obvious. If you rest way too long (10+ minutes), you’re body starts slipping out of ‘exercise’ mode – your heart rate drops, blood leaves the muscles, and your nervous system relaxes. While 5+ minutes of rest might be ideal for strength and powerlifting (where full recovery between sets is the goal for retaining strength), hypertrophy is about fatiguing the muscles. Long breaks aren’t optimal or practical if you want to keep intensity and volume without spending 3 hours in the gym.
So how much rest? The rest you take between sets should differ slightly depending on which exercise you are doing.
- Isolation exercises: Usually focus on one or two smaller muscles so recover faster and require less rest – (30–90s) is appropriate.
- Compound exercises: Use more muscles and stress the nervous system more so require slightly longer – (90–180s) are better here. In general, stick to the higher end for squats, bench press, and deadlifts, and around 2 minutes for everything else.

Between-session recovery: How to recover in time for your next session

Between-session recovery is where muscle growth happens. Training creates the stimulus but rest is where your body actually rebuilds and grows stronger.

The issue with not recovering enough: If you’re constantly hammering your body without enough rest, you’re digging a hole you can’t fill. This will lead to stalled progress and increased injury risk because your body simply isn’t being given time to recover and grow from sessions.
The issue with too much recovery: If you rest too much with long gaps between training sessions, you aren’t providing your muscles with enough frequent stimulus for muscle growth.
So how should you recover between sessions? Stick to the basics and be consistent.
- Volume: Optimising volume is covered above, so that’s a good place to start if you’re calculating your training schedule and rest days
- Sleep: Aim for 7–9 hours per night to allow your body enough time to repair.
- Nutrition: Support recovery by eating enough calories and plenty of protein.
- Stretching and mobility: Include basic stretching and mobility work to stay flexible, reduce soreness, and prevent injury.

FAQs💡

Should I train to failure?

Training to failure can be a powerful tool for hypertrophy, so use it as a tool, but not a rule. Training to failure on every set creates a lot of fatigue without much extra benefit compared to stopping 1–2 reps shy of failure. The goal is to push hard enough to stimulate growth without hammering your joints, nervous system, or recovery.

Here’s the best way to approach it:

Compound lifts (e.g. squats, deadlifts, bench press):
- Stick to 1–2 reps in reserve on most sets.
- You can push the last set to failure if it’s safe (e.g. with a spotter or safety equipment), but for super heavy lifts like deadlifts and squats, it’s usually smarter to leave 1 rep in reserve to protect your joints and nervous system.
Isolation lifts (e.g. bicep curls, tricep extensions, leg curls):
- You can train to failure more often here, especially towards the end of your workout when you’re already warm.
- For example, leave 1 rep in reserve on your first set, then push the next sets to failure.
- It’s also common to use advanced techniques like rest-pause sets or drop sets on the final sets of isolation exercises to push ‘past’ failure safely without huge risk.

What defines a muscle group?

The term ‘muscle group’ is fairly loosely defined and usually refers to a collection of muscles that work together to perform major movement patterns. This can be translated to ‘muscles in the same general location’. The major muscles groups are (in no particular order): Chest, Back, Shoulders, Arms, Legs, Abs.

A more important question for planning your training is: ‘Should you split these groups up even further when trying to figure out your weekly volume?’. Take the back for example – should you split it into upper back, mid-back, lats and lower back, aim for 16 sets per week on each? Probably not. Most back exercises, like bent-over barbell rows, naturally hit multiple areas at once.

So really its about using common sense and smart exercise selection to make sure all parts of the muscle group are covered, without obsessively isolating every muscle.

In practice:

You could split your back training into vertical pulls (e.g. pull-ups, deadlifts) and horizontal pulls (any form of rows)
Aim for 10 sets of each per week to cover the full back
Choose exercises that primarily target different areas, but understand that most exercises will overlap

What you don’t want to do is 16 sets of one movement like lat pulldowns, and neglect the rest of the back.

What should I do if I don’t see results?

This is a common problem for lifters just starting out or intermediates who are plateauing. There are many reasons this could be happening, but some of the main ones are listed below. Treat it as a checklist – start at the top and if you pass the check, move to the next one.

Are you being patient? You will not see significant results in your first 2 weeks of training. Read and apply this article for 8-12 weeks and come back.
Your diet isn’t right. Are you eating enough to grow/are you eating in enough of a deficit to lose body fat? Are you eating enough protein?
Your training isn’t right. Are you following the principles from this article? Are you progressively overloading? Are you consistently hitting your weekly volume in a smart way?
Your recovery isn’t right. Are you sleeping 7-9 hours per night? Are you overtraining (consider also your cardio routine – difficult to grow muscle if you’re marathon training)?

There are many other factors such as stress, hormones, genetics which may be holding you back, but if you optimise the above, you should start to see results.

Tips:

Get a training partner. This can really help with motivation and consistency, and is even better if they are more experienced than you in the gym.
Don’t compare yourself to what you see on social media, train to look like a better version of yourself.

Which workout split is best for hypertrophy?

All sensible workout splits are good, so you want to choose one you enjoy and can stick to consistently. Spend some time picking a split and then stick to it for 12 weeks and reassess. As long as the split follows the volume principles in this article, you should be fine.

Some good starting points are:

Full Body (3 sessions per week)
Upper/Lower x2 (4 sessions per week)
Push/Pull/Legs/Upper/Lower (5 sessions per week)
Push/Pull/Legs x2 (6 sessions per week)

Is soreness (DOMS) necessary for muscle growth?

DOMS (delayed onset muscle soreness – that muscle ache in the days after a workout) isn’t necessary for muscle growth, but is a good indicator that you’re doing something right.

You’ll typically feel less sore when using splits that spread volume more over the week. For example:

In a full body split, you might do 6 sets of chest three times a week (18 sets total)
In a push session, you might do 9 sets of chest twice a week for the same weekly volume
You’ll likely feel more chest DOMS after the push session, but that doesn’t mean it was a better session, just that more fatigue was concentrated into that one session.

That said, if you are progressively overloading effectively and training with intensity, it’s normal to have at least slight DOMS after a workout. If you’ve not felt this for a while, maybe take a look at your training sessions, intensity, exercise selection etc to make sure they’re optimal.

Will cardio hurt my muscle gains?

Cardio is absolutely fine while training for hypertrophy (it can even help in some ways), but there are a few key rules to follow if muscle growth is your priority:

Avoid intense cardio before lifting: Long or intense cardio (like long distance running, cycling or HIIT) before your workout will leave you pre-fatigued, which means you wont be able to lift as heavy or for as many reps. This limits your hypertrophy stimulus from that session.
Adjust your calorie intake to match your activity level: Cardio burns calories. If you’re trying to bulk up and put on muscle, make sure you’re still in a true calorie surplus by factoring in how many calories you’re burning during cardio. Otherwise, you may end up only maintaining or even losing weight without realising.
Factor cardio into your recovery: Hard cardio sessions still tax your body. Don’t fill all your gym rest days with intense cardio, especially if you’re already training hard. The exception is walking, which is low-impact and easy to recover from so you can do that pretty much daily. Aim for at least one full rest day per week, and for beginner lifters, probably even more.

In some ways, cardio can actually support hypertrophy:

Light cardio improves blood flow and can reduce soreness on rest days
Better cardiovascular fitness helps you recover faster between sets and maintain performance across longer workouts
A solid cardio base makes cutting fat easier, as you won’t be going from zero to 100 when it’s time to cut down

Closing Thoughts 📌

There’s so much advice on the internet about how to grow muscle, different techniques, different workout splits, new exercises, and so on. This article hopefully collates the important bits and gets them down on paper rather than contributing to the noise. It really isn’t rocket science, but I think people lose motivation fast because they see the body that they want on social media, but don’t look anything like it after 3 weeks of training. Don’t chase hacks, quick fixes, 30 day challenges etc – chase consistency, set achievable goals and work towards them over time. Above all, enjoy the process.

Notes 📝

Notes

How can we use advanced techniques to optimise hypertrophy, eg drop sets, rest pause sets, partial reps?

Definitions

Concentric Phase: The positive phase of an exercise, where the muscle shortens under load.
Example: Pushing the barbell upwards in a bench press or pulling the bar down in a lat pulldown.

Eccentric Phase: The negative phase of an exercise, where the muscle lengthens under load.
Example: Lowering the barbell to your chest in a bench press or releasing the bar upwards in a lat pulldown.

Muscle Tension: The force your muscles experience when stretching and contracting under load. Controlled movements and consistent tension are essential for hypertrophy.

Rate of Perceived Exertion (RPE): A subjective scale (1-10) used to measure the intensity of an exercise.
1 = Minimal effort; 10 = Maximum effort.
