The best workout plan for gaining muscle

Want to build serious muscle? Then you need more than just a random assortment of workouts – you need a plan. Muscle growth isn’t just about lifting heavy weights. It’s about progressive overload, smart exercise selection, dialed in nutrition and giving your muscles the recovery they need to grow bigger and stronger.
Whether you're just starting out or looking to break through a plateau, the right strategy will make all the difference. A well-structured workout plan should prioritize compound lifts for maximum strength, include isolation exercises to target specific muscles and allow for proper recovery to keep you progressing.
Without a plan, you’re just guessing. A structured program ensures you’re hitting each muscle group effectively, using the right rep ranges for hypertrophy and consistently pushing past your limits. Pair that with solid nutrition and tracking your progress and you'll be on the fast track to real gains.
In this guide, we’ll break down the science of muscle growth, show you how to build an effective workout plan and give you a weekly training routine designed to maximize results – whether you're training at the gym or at home with free weights.
Ready to start building muscle the right way? Let’s go.

The key principles to gain muscle
Building muscle isn’t just about lifting heavy – it’s about consistency, progression and recovery. If you want real gains, you need a plan that keeps you challenging your muscles, training with purpose and allowing for proper recovery. Here’s how to do it:
1. Progressive overload
Your muscles grow when they’re forced to adapt to increasing stress. That’s where progressive overload comes in. To keep making gains, you need to gradually increase the challenge by:
Adding more weight to your lifts
Doing more reps or sets
Improving your form and control
Reducing rest time to push intensity higher
If you’re lifting the same weights for the same reps every week, your progress will eventually stall. Aim to keep pushing your limits – that’s how you grow.
2. Training frequency
How often should you train to build muscle? Well, it depends on your schedule, but we recommend 2-3 days at the minimum, divided into separate training splits. Some of the most common splits include:
Push-pull-legs (PPL): Hitting each muscle group twice per week
Upper-lower split: Focusing on the upper and lower body on separate days
Body part splits: Training individual muscle groups on different days
No matter which split you choose, consistency is key to your goals. Train with enough frequency and volume, and you’ll see steady progress.
3. Proper rest and recovery
Muscles don’t grow while you’re lifting – they grow while you recover. Skip rest, and you risk burnout, injury and stalled progress. Here’s what you should prioritize:
7-9 hours of quality sleep every night to repair and build muscle
1-2 rest days per week to avoid overtraining
Active recovery (light movement, stretching, mobility work) to keep your body primed to build muscle
If you train hard but don’t recover well, you’re leaving gains on the table. Remember: recovery isn’t optional – it’s a key part of the process.
With these principles in mind, you’ll build muscle faster, avoid plateaus and stay injury-free.
Now, let’s get to work on your muscle-building plan.

Short on time but looking to achieve maximum gains? We’ve got you covered with these 7 hacks.
Designing a workout plan for muscle gain
If you want real muscle growth, a structured workout plan is the key to consistent progress and balanced development. To maximize hypertrophy, you need to hit each muscle group with the right mix of volume, intensity and recovery.
Here’s how to build an effective muscle-building workout plan:
Choose a training split – Decide how many days you’ll train and how to divide your workouts between the key body parts.
Prioritize compound movements – Focus on big lifts that engage multiple muscle groups for maximum strength and growth.
Incorporate isolation exercises – Use accessory movements to target specific muscles.
Follow the right sets & reps – Stick to 3-5 sets of 6-12 reps per exercise for hypertrophy.
Track your progress over time – Log how heavy and how much you’re lifting during each session. Gradually increase weight, reps or intensity to keep your muscles adapting and growing.
Now, let’s look at some of the moves to include in your workout routine for maximum muscle growth.
Exercises to take your gains to the next level
Whatever workout split you opt for, you should include a mix of compound and isolation exercises in your routine. It’ll challenge your body in new ways and help you hit your goals fast.
Compound exercises
These moves help save time and help you build a foundation quicker than isolation exercises. Over time, they’ll help you lift heavier loads and build overall strength. Compound exercises are also great for functional fitness, helping you move easier through life.
1. Barbell bench press
The bench press is a powerhouse move for building your chest, shoulders and triceps. Unlike push-ups, which have a strength ceiling (ie. your own body weight), the bench press lets you keep stacking weight and pushing past limits. Whether you use dumbbells or a barbell, this upper-body essential is your key to serious strength gains.
2. Barbell back squat
Squats are the ultimate strength-building move – a must-have in any muscle-building plan. Nail your form, and you’ll fire up your glutes, quads and hamstrings while strengthening your core and entire posterior chain. The payoff? More power in your workouts, plus better balance and mobility in everything you do.
3. Barbell deadlift
A deadlift fires up your entire body, making it one of the most powerful lifts you can master. Your quads, hamstrings and glutes drive the movement, while your core, lats and back keep everything locked in. Never dread picking up a heavy item again – the deadlift builds real-world strength you’ll use every day.

Isolation exercises
Need to zero in on a specific muscle? Isolation exercises are your go-to for building strength, fixing imbalances and activating any muscles you may have missed. They’re also a smart way to train around injuries or give overworked muscles a break while still making progress.
1. Bicep curls
Bicep curls are a classic for a reason – they’re one of the best ways to build arm strength and shape. By isolating your biceps, you can target them directly, increasing muscle size and definition. Plus, stronger biceps improve your performance in other lifts and everyday tasks, giving you more power and control.
2. Tricep extensions
You can’t fill out your sleeves with just bicep curls – your triceps are just as important. Strong triceps help you with pressing movements (like the bench press), and help improve overall arm strength. Tricep extensions aren’t limited to one piece of equipment – you can switch things up with dumbbells or a tricep rope attached to a cable machine, like the Centr 2 Home Gym.
3. Dumbbell fly
Dumbbell flys are a game-changer for sculpting a fuller, more defined chest. This move isolates your pectoral muscles, stretching and contracting them to increase size and shape. As a bonus, you’ll also improve flexibility and range of motion in your shoulders – what’s not to love?
How to select the right set & rep ranges
The right balance of sets and reps is crucial for muscle growth. To build muscle efficiently, you need to find the sweet spot between volume (total workload) and intensity (weight used) while ensuring steady progression.
For muscle hypertrophy (growth), here are some general guidelines to aim for.
- 6-12 reps per set. This provides enough resistance to challenge your muscles and stimulate growth.
- 3-5 sets per exercise. Provides the volume needed for adaptation.
- 60-90 seconds rest between sets. Allows recovery without dropping intensity.
How to pick the right weight for you
Not sure how heavy to go? Here’s a good rule of thumb: always aim for two reps left in your tank. This means ensuring good form for your entire working set, with enough gas for two good reps – no swinging or cheating! As Centr expert Torre Washington says: “Quality over quantity, always.”
Looking to really push your limits? Try strength climbers – A-list stuntman Bobby Holland Hanton’s go-to routine. Start by completing eight reps of an exercise, then increase the load for the next two sets to keep your muscles guessing and growing.

Don’t forget – you (and your muscles) are what you eat.
Nutrition is critical for muscle-building
Training hard is only half the battle – your diet is just as crucial for building muscle. To maximize muscle growth, you need to fuel your body with the right nutrients to support repair and recovery. Your calorie needs will be increased when you’re looking to bulk up, so you’ll need get pretty serious about eating.
Centr’s Build Strength and Gain Muscle goals have inbuilt meal plans that help you calculate the calories you need, and will provide you increased calories via extra snacks.

Remember, everybody’s nutrition needs are different – your requirements will vary according to a range of factors, including:
How hard and often you train
Your body composition
Your muscle mass
Your age, metabolism and genetics
Your specific goals
Remember to track your progress
To keep building muscle, tracking your progress and making adjustments is a game-changer. Sticking to the same routine without progression will eventually lead to plateaus, so it’s important to keep challenging yourself. Here’s how you can keep the gains coming:
Track strength and performance
Use a workout log, app or notebook to track your exercises, weights, sets and reps. The Centr app offers a handy logbook within workouts, so you can track your strength gains over time. Challenge yourself to increase weight or reps each week – that’s the key to progressive overload and muscle growth.
Monitor physical changes
Snap weekly progress photos to see how your muscle definition is improving. Measure your body weight and muscle circumference (arms, chest, legs) every few weeks to check for changes.
Prioritize recovery
Make sure you’re getting enough sleep and taking rest days to allow your muscles to repair and rebuild. Add some mobility work on your rest days to prevent injuries and enhance your performance.
By tracking your progress and making smart adjustments on your muscle-building journey, you’ll stay on the fast track to continuous gains. Remember: consistency and patience will take you all the way.
