3‑day full body workout: a plan for busy lifters
A 3 day full body workout for busy lifters: three sample sessions (A, B and C), how hard to train, how to progress, and what to do when a week falls apart.
A 3 day full body workout trains every major muscle in each session, three times a week, for example Monday, Wednesday and Friday. It is one of the most time-efficient ways for busy lifters to train each muscle often, and a missed session costs you less than it would on a split. Below are three sessions to rotate, how to set your weights, and how to keep progressing.
Why full body works on three days
The case for full body rests on a simple finding. A 2019 meta-analysis by Schoenfeld, Grgic and Krieger found that when weekly volume is the same, training frequency does not meaningfully change muscle growth. The authors concluded that lifters can choose a frequency based on preference.
That means three full body sessions can match a four or five day split for growth, as long as the total hard sets are similar. You get there with fewer gym visits.
Full body has other practical benefits:
- Each session needs fewer sets per muscle. Two or three sets per muscle per session adds up to 6 to 9 a week.
- Missed sessions hurt less. If you skip a day, every muscle was still trained at least twice that week.
- You practice the main lifts often. Squatting, pressing and pulling more than once a week helps you get better at them.
Full body is also common in research on trained lifters. In one study on rest periods, experienced men followed three total body sessions a week for eight weeks. The group that rested 3 minutes between sets gained more strength, and more thigh muscle, than the group that rested 1 minute. That is also a good reason not to rush your rest on the big lifts.
How to schedule a 3 day full body week
Leave at least one rest day between sessions when you can.
| Option | Mon | Tue | Wed | Thu | Fri | Sat | Sun |
|---|---|---|---|---|---|---|---|
| Classic | A | Rest | B | Rest | C | Rest | Rest |
| Weekend-friendly | Rest | A | Rest | B | Rest | C | Rest |
| Two in a row | A | Rest | Rest | B | C | Rest | Rest |
If two sessions fall back to back, put Session C second, because it uses lighter loads. Keep the order A, B, C even when the days move.
The three sessions
Each session has one main lower body lift, one press, one pull and a few accessories. The heavy emphasis rotates, so you are not squatting and deadlifting heavy on the same day.
Session A: squat and bench
| Exercise | Sets | Reps | Rest |
|---|---|---|---|
| Back squat | 3 | 5–8 | 2–3 min |
| Bench press | 3 | 6–8 | 2–3 min |
| Chest-supported row | 3 | 8–10 | 2 min |
| Romanian deadlift | 2 | 8–10 | 2 min |
| Lateral raise | 2 | 12–15 | 60 s |
| Cable curl | 2 | 10–12 | 60 s |
Session B: deadlift and overhead press
| Exercise | Sets | Reps | Rest |
|---|---|---|---|
| Trap-bar or conventional deadlift | 3 | 4–6 | 3 min |
| Overhead press | 3 | 6–8 | 2 min |
| Pull-up or lat pulldown | 3 | 6–10 | 2 min |
| Split squat | 2 | 8–10 each leg | 90 s |
| Triceps pushdown | 2 | 10–12 | 60 s |
| Hanging knee raise | 2 | 10–15 | 60 s |
Session C: lighter and higher reps
| Exercise | Sets | Reps | Rest |
|---|---|---|---|
| Leg press or hack squat | 3 | 10–12 | 2 min |
| Incline dumbbell press | 3 | 8–12 | 2 min |
| Seated cable row | 3 | 10–12 | 90 s |
| Lying or seated leg curl | 3 | 10–12 | 90 s |
| Face pull | 2 | 12–15 | 60 s |
| Incline curl and overhead triceps extension | 2 each | 10–15 | 60 s |
Across the week, chest, back, quads and hamstrings each get roughly 6 to 9 direct sets, plus indirect work from the compound lifts. Each session takes about 50 to 60 minutes.
Swap any exercise for a close alternative your gym has. A goblet squat can replace a back squat, and a dumbbell row can replace a chest-supported row.
Choosing your starting weights
In the first week, pick weights you could lift for 2 or 3 more reps at the top of each range. It should feel comfortable. Write down every set. That first week is your baseline, not a test.
From week two, start progressing. Starting a little light gives you several weeks of steady gains before things get hard.
How hard to push
Stop most sets with 1 to 3 reps in reserve. On heavy squats and deadlifts, stay around 2 or 3. On curls, raises and leg curls, you can go closer to failure.
Training to failure on every set is not needed. A 2023 meta-analysis by Refalo and colleagues found no clear advantage for training to momentary failure over stopping a little short, for muscle growth. In a full body plan, where you train the same muscles again two days later, stopping short also helps you recover in time.
How to progress
Use double progression. Work within a rep range, add reps until every set hits the top of it, then add weight.
The ACSM position stand on progression suggests adding 2 to 10% to the load once you can beat your target by one or two reps. Smaller jumps suit upper body lifts.
Here is the back squat from Session A, 3 sets of 5–8:
| Week | Weight | Reps per set |
|---|---|---|
| 1 | 70 kg (154 lb) | 8, 7, 6 |
| 2 | 70 kg (154 lb) | 8, 8, 7 |
| 3 | 70 kg (154 lb) | 8, 8, 8 |
| 4 | 75 kg (165 lb) | 6, 6, 5 |
Because each main lift appears once a week, progress on it comes week to week, not session to session. That is fine. Steady small gains over months add up.
For lifts like overhead press and lateral raises, a 2.5 kg (5 lb) jump can be too big. Stay at the same weight longer and add reps, or use smaller plates if your gym has them.
Fitting it into a busy week
Full body is forgiving, which is the point for busy lifters. A few rules keep it that way:
- Short on time? Do the first three exercises only. That covers legs, a press and a pull in about 35 minutes.
- Missed a session? Do the next one in order. Do not try to squeeze two sessions into one day.
- Only two days this week? Do A and B. Pick up with C next week.
- Want more? Add a fourth short session for arms and shoulders, or move to an upper lower split.
Common mistakes
- Too many exercises. Five or six per session is plenty. More makes sessions long and the last sets sloppy.
- Heavy everything, every day. Rotate the heavy lifts so each day has one hard lower body lift.
- Cutting rest to save time. Drop an accessory instead. Heavy compound lifts need 2 to 3 minutes.
- Skipping the warm-up. Do two or three lighter ramp-up sets before your first big lift.
- Not tracking. Without your last numbers, you cannot know whether to add a rep or add weight.
If an exercise causes pain rather than normal effort, stop and see a qualified professional.
How RepChief helps
RepChief gives you a free starter plan on the days you choose and lets you log every set, with your history and personal bests in one place. With RepChief Pro, Chief, the coach, can adjust the plan when your week changes or you stall on a lift.
