Workout Plan for Muscle Gain: A Weekly Routine That Works
Workout Plan for Muscle Gain: A Weekly Routine That Works
The best workout plan for muscle gain trains every major muscle at least twice a week, adds up to roughly 10 hard sets per muscle weekly, and raises the demand on your muscles gradually. The split matters less than doing it consistently and recording what you lift. That is where Brolick helps: it learns from your logged sessions and suggests what to do next, so you are not guessing.
TL;DR
- Train each major muscle group about twice a week: full body on three days, or upper/lower on four.
- Aim for roughly 10 to 20 hard sets per muscle group per week, in the 6 to 12 rep range, finishing most sets with 1 to 3 reps left in the tank.
- Rest 1.5 to 3 minutes between working sets and leave about 48 hours before hitting the same muscle hard again.
- Add load, reps or sets over time and log every session. Progress only shows up if you can see it.
- Eat roughly 1.4 to 2.0 g of protein per kg of body weight a day.

What actually drives muscle growth
Muscle grows when you give it a stimulus it is not used to, then recover. The American College of Sports Medicine (ACSM) 2026 position stand reviewed 137 systematic reviews covering more than 30,000 participants. It found hypertrophy (muscle growth) was enhanced by higher weekly volumes, meaning at least 10 sets per week, and by eccentric overload, which is emphasising the lowering part of a lift.
The same review found that equipment type, exercise complexity, set structure and time under tension did not consistently change results. In plain terms: a simple plan done hard and regularly beats a clever one done half-heartedly. Stuart Phillips, an author of the position stand, makes the same point: training all major muscle groups at least twice a week matters far more than chasing a perfect plan.
NASM’s trainer guide names three drivers of growth: mechanical tension (load moved through a full range of motion), metabolic stress (the burn) and muscle damage (soreness). Build the plan on tension, treat the others as extras, and do not chase soreness. If you are too sore to train again within 48 hours, the session gave you a worse stimulus, not a better one.
Choose your weekly split
The guide says full-body training works well at three days a week and upper/lower at four, and that the best split is the one you actually complete. Frequency itself is not magic. A 2026 meta-analysis of 16 studies found no significant difference in hypertrophy between training a muscle one to two times a week and three to six times a week when total weekly volume was matched.
| Days per week | Split | Best for |
|---|---|---|
| 3 | Full body (A/B/A, then B/A/B) | Beginners, busy schedules |
| 4 | Upper / Lower / Upper / Lower | Most intermediates |
| 5 to 6 | Push / Pull / Legs or body-part splits | Experienced lifters with time to recover |
One caution on the five-day body-part splits you see online, where each muscle is trained once a week. Evidence slightly favours training a muscle two or more times weekly, especially when volume is high, according to Weightology’s frequency review. For most people, three or four days is the sensible place to start.
Sets, reps, load and rest
NASM’s guidance gives a clear working range:
- Volume: roughly 10 to 20 hard sets per muscle group per week.
- Load and reps: about 65 to 85 per cent of your one-rep max, which is around 6 to 12 reps.
- Effort: most sets finish with 1 to 3 reps in reserve, meaning you could have done that many more with good form.
- Rest: 1.5 to 3 minutes between working sets.
Why does volume matter? A 2021 review cites a 2017 meta-analysis showing muscle gains of about 5% for fewer than 5 weekly sets, about 7% for 5 to 9 sets and about 10% for 10 or more. More sets help, up to a point your recovery can support.
How many exercises per workout
There is no single number. A rule of thumb from Men’s Health is 10 to 20 sets per muscle group per week, roughly three to six exercises. Small muscles such as biceps, triceps and shoulders need fewer, perhaps one or two exercises, because their movements are simpler. Per workout, that works out as:
- Three full-body days: a squat, a hip hinge, a press, a pull and a couple of isolation moves.
- Four-day upper/lower: at least one press and one pull on upper days, plus a couple of isolation exercises.
Pick compound lifts first
The 2021 review recommends prioritising multi-joint exercises and including at least one leg press or squat pattern, one upper-body pull such as a pull-up, and one upper-body push such as a bench press. Isolation work like curls and lateral raises then fills the gaps.
A sample week you can start with
This four-day upper/lower week hits each muscle twice. Use a weight that leaves 1 to 3 reps in reserve on every set.
| Day | Exercises | Sets x reps |
|---|---|---|
| Monday (upper) | Bench press, chest-supported row, overhead press, lat pulldown, triceps pushdown, biceps curl | 3 x 6 to 10 on the main lifts, 2 x 10 to 12 on the rest |
| Tuesday (lower) | Squat, Romanian deadlift, leg press, leg curl, calf raise | 3 x 6 to 10 on the first two, 2 to 3 x 10 to 12 on the rest |
| Thursday (upper) | Incline dumbbell press, pull-up or assisted pull-up, seated row, lateral raise, curls, triceps extension | 3 x 8 to 12 |
| Friday (lower) | Deadlift or hip thrust, split squat, leg extension, leg curl, calf raise | 3 x 8 to 12 |
Counting the main lifts and accessories, most muscles land in the 10 to 20 weekly sets range. If you only have three days, run the same exercises as two full-body sessions plus a third that rotates emphasis. For a beginner-focused three-day structure, our guide to the Starting Strength novice programme explains a simple template. If you are using a machine for pressing, our chest press machine guide covers technique and progression.
Progressive overload: the part that keeps working
Progressive overload means gradually increasing the stimulus on the muscle. The ACSM position stand lists the levers: load, volume, frequency, exercise selection or duration, even if only slightly. You do not need to add weight every week. A simple order:
- Stay in your rep range and add reps to each set.
- When you reach the top of the range on every set, add a small amount of weight and drop back to the bottom of the range.
- If volume is comfortable and recovery is good, add a set to a lagging muscle.
This only works if you remember last week’s numbers. That is the practical reason to log every set. It also shows you when you have stalled, so you can change something instead of repeating the same session for a month.
Blocks, deloads and honest timelines
NASM suggests training blocks of 4 to 6 weeks with planned progression, then varying exercise selection or emphasis. It also advises deload weeks, meaning a lighter week, when performance stalls. Expect noticeable changes in 8 to 12 weeks, faster if you are new to lifting. Track loads, reps, measurements and photos, because scale weight alone tells an incomplete story.
Recovery and protein
Growth happens between sessions. NASM’s guidance is roughly 48 hours before training a muscle hard again and 7 to 9 hours of sleep. If soreness is making you wonder whether to train, read when to train with muscle soreness and when to rest. Spacing sessions sensibly also matters for how often you can train; one article on recovery between sessions makes a similar point for young athletes: more hours is not always better.
On protein, the ISSN position stand says 1.4 to 2.0 g per kg of body weight per day is sufficient for most exercising people building muscle. It suggests doses of 0.25 g per kg, or 20 to 40 g, spread through the day. For an 80 kg person that is about 112 to 160 g daily. If you have a kidney condition or are pregnant, speak to your GP or a registered dietitian before raising your protein intake.
Fitting the plan to your life
The ACSM says programmes should be individualised around goals, enjoyment and safety, because a plan too demanding to maintain stops working. If time is short, the 2021 review suggests a minimum of 4 weekly sets per muscle group in the 6 to 15 rep range works as a time-efficient floor, with higher-volume blocks followed by lower-volume blocks for maintenance. Trying a few approaches is easier when you can compare them; our guide to choosing workout recommendations that fit you walks through how.

How Brolick keeps the plan working
A written plan is static. Your body is not. Brolick tracks your workouts, logs progress and analyses your training patterns, performance and preferences to build adaptive plans. It recommends training intensity, rest periods and exercise selection, detects plateaus and suggests daily routines based on your history. You can also build custom routines. Brolick Pro is the optional subscription in the Android app on Google Play, and we do not share your data or use it to train external AI.
If you want the sample week above to adjust as you get stronger, try Brolick.
Our view on muscle-gain plans
Most people do not fail at building muscle because they picked the wrong split. They fail because the plan stops fitting them: it ignores a missed session, a stalled lift or a week of poor sleep, and they quietly drift away from it.
The research agrees with that. Volume and consistency drive results, and individual response varies. So we built Brolick to learn from your training history rather than hand you the same static sheet. When it sees a plateau, it adjusts intensity, rest or exercise choice. That is the job a good coach does between sessions, and it is why we think an adaptive plan beats a fixed one.

FAQ
How many days a week should I train to gain muscle?
Three to four days suits most people. Three full-body sessions or four upper/lower sessions both train each muscle about twice a week, which is the pattern the ACSM and NASM guidance supports. Pick the one you can keep up.
How many sets per muscle do I need each week?
Aim for roughly 10 to 20 hard sets per muscle group per week. The 2026 ACSM position stand found that at least 10 weekly sets enhanced hypertrophy. Beginners can start nearer 10 and build up as recovery allows.
How much protein do I need to build muscle?
The ISSN position stand says 1.4 to 2.0 g per kg of body weight per day is sufficient for most people. Spread it across the day in doses of about 20 to 40 g.
How long until I see results?
NASM says noticeable changes typically take 8 to 12 weeks, with newer lifters progressing faster. Track lifts, measurements and photos rather than relying on scale weight alone.
