Full-body workout plan for intermediates: 3 days a week, 12 weeks

Choosing your starting weightEmerging evidence

Warm up, then pick a weight you think you could lift about 10 to 12 times at most. Do the bottom of the rep range (for 8 to 12, do 8) and ask: how many more could I have done with good form? Two or three more: that is your weight. Five or more: go up one step next set. None or one: go down one step.

For bodyweight moves, choose the version (the easier or harder option on each move's page) where you reach the bottom of the rep range with 2 or 3 reps to spare.

In the first two weeks, stop each set with 3 or 4 reps to spare. Most people misjudge how many reps they have left by about one, and you are still learning the movements.

Progressing week to week: double progressionEmerging evidence

Each exercise has a rep range, such as 8 to 12. Keep the weight the same and add reps, set by set and session by session, while still stopping 1 to 3 reps short of failure.

When every set reaches the top of the range, add the smallest weight step you have (roughly 2 to 10%, smaller jumps for the upper body and small muscles) and go back to the bottom of the range. Adding reps and adding weight both work; this rule uses both.

With body weight, add reps, then slow the lowering, then move to the harder option. If a lift stalls for 2 or 3 sessions, hold the weight, check your sleep and food, and consider a lighter week.

How hard each set should feelStrong evidence

You do not need to train to failure. Stopping 2 or 3 reps short, often written as 2 to 3 reps in reserve (RIR), gives similar results for most people.

Compound lifts stay at 2 to 3 reps in reserve, on the heavy day too. On the light day, machine lifts can stop 1 to 2 reps short, and the last set of isolation moves such as leg curls, raises and arm moves can go to 0 to 2.

Rest between setsEmerging evidence

Heavy compound lifts in sets of 5 to 8 (squat, deadlift, bench press, overhead press, chin-up): 2 to 3 minutes. Other compound lifts in sets of 8 to 12: about 90 seconds to 2 minutes. Isolation moves such as raises, curls, extensions and calf raises: 60 to 90 seconds.

For muscle growth, resting more than about a minute gives a small advantage, with no clear extra gain past about 90 seconds. For strength the evidence on rest is mixed: 1 to 2 minutes is enough for beginners, and trained lifters may do better with longer rests on heavy lifts.

Short on time? Pair two moves that do not compete, such as a press with a row or a leg move with a core move, and rest after the pair. Supersets like this cut session time by about a third to a half while keeping the sets.

Lighter weeks (deloads)Mixed evidence

Not compulsory, especially for beginners. Take one in week 8, as planned here, or sooner if your performance drops for two sessions in a row and you feel run down or achy: same days, same exercises, about half the sets, and weights that feel easy (4 or more reps in reserve). Then restart at your previous weights.

Deloads are common practice: in a survey of competitive strength and physique athletes they lasted about a week, roughly every 5 to 6 weeks. Direct evidence is thin: three small trials. In trained adults, a full week off mid-programme did not change muscle growth but slightly reduced strength gains. In one small trial in 19 untrained men, with no control group, two lighter weeks neither held back nor added to gains; the second came just before testing, so it also worked as a taper. After very high-volume training, a lighter week and a week off gave similar results in 30 trained men. So a lighter week looks better than a week off if strength matters.

Warm-up and cool-downEmerging evidence

Warm up with 3 to 5 minutes of easy movement, the moves listed at the start of each session, then 1 or 2 lighter sets of the first lift. A short warm-up specific to the exercise is enough.

The cool-down is optional. Its stretches are there for comfort and flexibility; they do not add strength or muscle.

Missed days, soreness and when to stop

Missed a session? Do the next one in the order rather than doubling up. Muscle soreness for a day or two after a new exercise is common and fades as you repeat it.

Stop and get medical help for chest pain or pressure, unusual breathlessness, dizziness or fainting. If a joint pain is sharp, gets worse during a set or lingers into the next day, swap to the move's easier option, and see a clinician if it persists.

WHO notes that people without contraindications generally do not need medical clearance before light or moderate activity. If you have a heart, lung or metabolic condition, are pregnant, or have osteoporosis with fractures, ask your clinician first.

How much training this isStrong evidence

Counting direct sets in the build phase, this plan gives about 8 hard sets a week for the chest, 9 for the back, 7 for the shoulders (presses and raises), 8 for the quads plus 3 sets of trap bar deadlifts that also work them, 10 for the glutes and hamstrings, and 2 direct sets each for the biceps and triceps on top of the presses, rows and pulldowns. At home it's about 10 for the chest, 9 for the back, 8 for the shoulders, 10 for the quads and 10 for the glutes and hamstrings.

More weekly sets build more muscle, with diminishing returns that arrive sooner for strength than for size. The 2026 ACSM position stand saw extra growth from about 10 or more sets per muscle a week, and a review of time-efficient training suggests about 4 hard sets a week as a reasonable floor for busy people.

That clears the 4-set floor for every muscle and comes close to the 10-set mark for most. Want more for one muscle? Add 2 sets of it to the light day.

Full body or split: similar resultsStrong evidence

When weekly sets are matched, full-body and split routines give similar strength and muscle gains, and how often you train a muscle matters little for growth. So the choice is about your schedule, session length and what you enjoy.

Sources 18, 19, 17

How often to train each muscleStrong evidence

A 2016 review of 10 studies found that training a muscle twice a week grew it more than once a week, which is where the common advice to train each muscle at least twice a week comes from. A 2019 update of 25 studies found no meaningful difference between once, twice or three times a week once weekly sets were matched, and the largest analysis since, of 67 studies and 2,058 people, found the effect of frequency on growth was compatible with negligible.

Strength is a little different: in 22 studies it rose with more sessions a week, though not once weekly sets were matched, and in the larger analysis it kept rising with frequency, with diminishing returns. So training each muscle about twice a week or more is a practical way to fit in enough sets and practise your lifts, not a rule. This plan trains each muscle three times a week; twice would also work.

Why a heavy, a moderate and a light dayMixed evidence

Heavier sets of 5 to 8 build more maximal strength, while muscle grows about as well with light or heavy weights when the sets are hard, so a week with both covers both.

Whether changing the load from day to day adds anything is mixed. In a review of 35 studies with matched sets, planned changes in load gave slightly more one-rep maximum strength than an unchanging programme, and changing it day to day did a little better than changing it every few weeks (both small effects), with no difference in muscle growth. A review of 17 studies found the two patterns worked equally, and the 2026 position stand of the American College of Sports Medicine (ACSM) found that this kind of planning, periodisation, did not consistently change results. So treat the three days as a sensible way to organise the week, not a proven upgrade: steady progress on your lifts matters more.

Main lift firstEmerging evidence

In 11 studies, strength rose most in the exercises done at the start of a session, while muscle growth didn't depend on the order. So each day opens with its main lift, and the ACSM position stand lists lifting an exercise early in the session among the things that improve its strength.

Sources 25, 1

Machines or free weights: both workEmerging evidence

In 13 studies of 1,016 people, machines and free weights built similar strength, and similar muscle in a few small studies, when compared directly, though people got best at the equipment they trained with. The light day uses machines because they're quick to set up and guide the path of each lift, which makes hard, lighter sets easy to do safely (our editorial choice); any of them can be swapped for its free-weight version.

Sources 26, 1

Change exercises on purpose, not every sessionEmerging evidence

A review of 8 studies in 241 young men found that some planned variety may help a muscle grow along its whole length and help strength, but changing exercises often and at random may hold gains back. Keep the same exercises for the 12 weeks, then change one or two a day.

Source 27

Cardio does not cost you muscleStrong evidence

Doing cardio as well as strength training does not reduce muscle growth or maximal strength. It can blunt explosive strength, such as jumping, mainly when both are done in the same session; keep them at least 3 hours apart if that matters to you.

Source 28

At homeStrong evidence

Muscle grows with light or heavy weights when the sets are hard, and home-based and band training improve strength. When your heaviest dumbbells feel light on the heavy day, slow the lowering to 3 seconds and pause at the bottom, then move to harder versions.

Sources 22, 1

Who this plan suitsStrong evidence

Anyone who likes three sessions a week and has about 8 weeks of lifting behind them, because the heavy day uses sets of 5 to 8. New to the gym? The 3-day plan for beginners comes first. The old advice that beginners should do two or three full-body sessions a week rested on three small studies with 59 people in all, so the best plan is the one you'll keep doing.

How to adapt it

Our suggestions, with the evidence where there is some:

• Two days a week: the 2-day plan, or the heavy and moderate days only (each muscle then gets about two-thirds of the sets).
• Four days: rotate heavy, moderate, light and heavy across Monday, Tuesday, Thursday and Friday. Weekly sets rise by about a third, with diminishing returns, so drop back if your lifts stall.
• Short on time: pair each press with a row, and each leg move with a core move, resting after the pair; supersets like this can cut the time by about a third to a half. On a busy week, the 20-minute full-body strength workout twice is enough to keep going.
• No equipment: the 3-day home plan's no-equipment track.
• Sore knees: a shorter range on the squat and leg press, and more hinge work; see the knee pain guides.
• Sore back: the leg press or a lighter Romanian deadlift instead of the trap bar deadlift; see the low back pain guide.
• Sore shoulders: neutral-grip presses, and lateral raises with your thumbs slightly up.
• Missed a week: one session at your last weights, then carry on. After 2 or more weeks off, go back to the weeks 1 to 2 doses.
• Pregnant: the pregnancy workout plan. Had a baby in the last few months: the postpartum workout plan.
