The 3-Day Workout Split: Three Ways to Run It

Option 1: Full body A/B, three times a week

Every session trains legs, a push and a pull, so each muscle is trained three times a week and each lift comes around three times every two weeks. That repetition is why full body is the default for the first year. If you have never trained before, the simpler 4-week beginner gym plan is the place to start; this version adds a second leg movement and arm work for when that plan feels routine.

Session A

1. Back Squat or Goblet Squat3 × 6–10

   Goblet squat until you can hold a 24 kg (about 55 lb) dumbbell for 10 clean reps, then move to the barbell.

2. Dumbbell Bench Press3 × 8–12

   Lower until the dumbbells are level with your chest, elbows about 45 degrees from your sides.

3. Lat Pulldown3 × 8–12

   Bar to the top of the chest, no leaning back past about 20 degrees.

4. Lying or Seated Leg Curl2 × 10–15

   The hamstring work this session would otherwise miss.

5. Dumbbell Lateral Raise2 × 12–15

   Light. Stop at shoulder height. Pressing does not cover the side of the shoulder well.

6. Plank2 × 30–45 s

   End the set when the hips sag.

Session B

1. Romanian Deadlift3 × 8–10

   Hips back, bar close to the legs, stop where your lower back starts to round.

2. Dumbbell Split Squat2 × 8–10 each leg

   Hold a rack with one hand if balance limits you before the legs do.

3. Incline Dumbbell Press3 × 8–12

   Bench at 30 degrees. Swap for a seated shoulder press every other cycle if you prefer.

4. Seated Cable Row3 × 10–12

   Pull to the bottom of the ribs and let the shoulder blades move forward on the way back.

5. Dumbbell Curl2 × 10–15

   Can be paired with the next exercise, alternating sets, to save five minutes.

6. Triceps Pushdown2 × 10–15

   Elbows pinned to your sides.

Rest 2 minutes on squats and Romanian deadlifts, 90 seconds on everything else. With a 10-minute warm-up, each session runs 45 to 55 minutes.

Option 2: Upper / lower / full body

Each muscle gets two sessions a week instead of three, but each session can hold more sets for it. The bigger practical win is the calendar: upper and lower train different muscles, so they can run on back-to-back days, which Option 1 cannot do well. Saturday upper, Sunday lower, Wednesday full body is a perfectly good week. It is also a natural step toward the four-day upper/lower split if a fourth day appears later.

Upper

1. Bench Press, barbell or dumbbell3 × 6–10

   The heavy press of the week.

2. Lat Pulldown3 × 8–12

   Or assisted pull-ups, if your gym has the machine.

3. One-Arm Dumbbell Row3 × 10–12 each arm

   Knee and hand on a bench, pull the dumbbell to your hip.

4. Seated Dumbbell Shoulder Press2 × 8–12

   Back supported.

5. Dumbbell Curl + Triceps Pushdown2 × 10–15 each

   Alternate the two, 60 seconds rest between sets.

Lower

1. Back Squat or Leg Press3 × 6–10

   The heavy leg movement of the week.

2. Romanian Deadlift3 × 8–10

   Done second, so the lower back is fresh enough for clean reps.

3. Bulgarian Split Squat2 × 8–10 each leg

   Rear foot on a bench. Bodyweight only for the first two weeks.

4. Leg Curl2 × 10–15
5. Standing Calf Raise2 × 10–15

   Two-second pause at the bottom.

Full body

1. Hip Thrust3 × 8–12

   Glutes without loading the lower back again after the lower day's Romanian deadlifts.

2. Leg Press2 × 10–15

   Moderate weight, 2 to 3 reps short of failure.

3. Incline Dumbbell Press3 × 8–12
4. Seated Cable Row3 × 10–12
5. Dumbbell Lateral Raise2 × 12–15

Upper and lower run 50 to 60 minutes. The full-body day is the shortest, about 45 minutes, which makes it the one to keep when a week goes wrong.

Option 3: Push / pull / legs, once each

Push is chest, shoulders and triceps; pull is back and biceps; legs is everything below the waist. On three days that means each muscle is trained hard once a week, so every weekly set has to fit into that one session. The full sessions, with every set and rep, live on the push/pull/legs routine page next to the 6-day version they come from, so the exercises carry over if you later move to six days. In outline:

• Push, Monday: bench press, standing overhead press and incline dumbbell press, 11 pressing sets in all, then lateral raises and two triceps exercises.
• Pull, Wednesday: pull-up or lat pulldown, barbell row and seated cable row, 11 back sets, then face pulls and two curl variations.
• Legs, Friday: back squat, Romanian deadlift, leg press, Bulgarian split squat, leg curl and standing calf raise.

Each day is 19 or 20 hard sets and 75 to 90 minutes. It works, and plenty of people enjoy a whole session on one area. The cost is practice: you squat once a week instead of two or three times, and a missed leg day means no leg training that week. Exercise swaps and how to progress it are on the same page.

Weekly hard sets per muscle on each option

Direct sets only, counting a set that ends 1 to 3 reps short of failure. Option 1 alternates A–B–A and B–A–B, so its numbers move a little between weeks.

Direct glute sets are hip thrusts, Romanian deadlifts and split squats. Squats, presses and rows also work glutes, shoulders and arms, so the real totals are higher than the direct numbers. All three land in a similar range of about 5 to 11 sets for the big muscles, which is where most people should start. The difference is how the sets are spread. Research comparing frequencies with equal sets finds little difference in muscle growth, so for most beginners the deciding factors are practice and schedule, not volume. When you want to add sets, how many sets per muscle covers how far to go and when.

Which option fits your week

There is no separate 3-day split for women. The options, sets and progression are the same; what changes is the priority. If glutes are the goal, Option 2 already loads them on two days; add 2 sets of hip thrusts to the end of the lower day and keep the leg curl, so hamstrings do not lose out. The beginner gym plan for women is Option 1 with that emphasis built in, for anyone starting from zero.

How to progress on any of the three

Use double progression: stay at one weight and add reps until every set reaches the top of the range, then add the smallest weight increase and drop back to the bottom. A worked example on the Romanian deadlift, 3 sets of 8 to 10, in Session B of Option 1:

Session B comes around three times every two weeks, so those five sessions span about three weeks. Use 5 kg (about 10 lb) jumps on squats and deadlifts early on, 2.5 kg (about 5 lb) on barbell presses, and the next dumbbell up, usually 2 kg or 2.5 kg (5 lb in most US gyms), on dumbbell work. On Options 2 and 3 each lift comes around once a week, so the same five sessions take five weeks. The logic behind it, and what to do when reps stop rising, is in progressive overload.

Days, rest days and missed sessions

• Options 1 and 3: Monday, Wednesday, Friday, or Tuesday, Thursday, Saturday. On Option 1, keep a rest day between sessions, because every session works the same muscles.
• Option 2: any three days, as long as the full-body day has a rest day on each side. Upper and lower can sit back to back. Saturday upper, Sunday lower, Wednesday full works.
• Missed a session: do the next one in order on your next training day. Do not do two sessions in one day to catch up.
• Missed a whole week: restart at the same weights. If more than two weeks, drop about 10 percent and work back up over two or three sessions.
• Rest days: walking, cycling or easy cardio is fine. Hard leg cardio the day before a squat or lower session costs you reps.

Common problems and the fix

• Legs too sore for the next session. Normal for the first two weeks. If it lasts longer, cut the leg exercises to 2 sets for a week, then build back.
• The bench press stalls but the squat keeps going. Upper-body lifts progress more slowly. Stay on double progression longer, earning reps before load, and use 1 kg (2–2.5 lb) jumps if the gym has fractional plates, before deciding anything is wrong.
• Sessions keep running long. Time your rest. Curls, raises and pushdowns need 60 to 90 seconds, not four minutes. If rest is honest and it still runs past 70 minutes, move from Option 1 to Option 2.
• Adding a fourth "arm day" or "ab day". Fine if recovery holds, but it is no longer a 3-day split. If you have four days, the workout split guide shows which layout to use.
• Changing exercises every few weeks. Keep the same exercises for at least two or three progression cycles. New exercises reset the numbers you are trying to beat.

Questions people ask

Is a 3-day split enough to build muscle?

Yes. The ACSM recommends two to three days a week for novices, and three sessions at the volumes above give the big muscles 5 to 10 hard sets a week, which is enough for steady progress in the first years if the weights keep going up.

Is full body or push/pull/legs better on three days?

Full body, for most people. It trains each muscle three times instead of once, so you practice the lifts more and a missed session costs less. Push/pull/legs is a reasonable choice for experienced lifters who prefer it.

Can I train three days in a row?

On Option 3, yes, because consecutive days train different muscles. On Option 2, upper and lower can run back to back, but keep a rest day either side of the full-body day. On Option 1, avoid it: every session loads the same muscles, so the second and third days start tired.

How long should each workout take?

45 to 60 minutes including warm-up for Options 1 and 2, and 75 to 90 for Option 3, which packs a muscle's whole week into one session. Rest 90 seconds to 2 minutes between most sets, longer on heavy squats and deadlifts.

Where do abs go?

Two sets of a plank, side plank or cable crunch at the end of any one or two sessions. Squats and Romanian deadlifts already work the trunk hard.

When should I move to four days?

When the work you need no longer fits in three sessions of about an hour, and you have a fourth day you can keep. Not because three days feels too simple.

Where these numbers come from

• American College of Sports Medicine position stand, Progression Models in Resistance Training for Healthy Adults (Medicine & Science in Sports & Exercise, 2009): two to three days a week for novices, moderate rep ranges and gradual load increases.
• Schoenfeld and colleagues, Effects of Resistance Training Frequency on Measures of Muscle Hypertrophy (Sports Medicine, 2016), and their 2019 follow-up in the Journal of Sports Sciences: twice a week beats once, but the gap mostly closes when weekly sets are equal.
• Schoenfeld and colleagues, Dose-response relationship between weekly resistance training volume and increases in muscle mass (Journal of Sports Sciences, 2017): more weekly sets produce more growth, with gains even at low volumes.
• CDC, physical activity guidelines for adults: muscle-strengthening activity on two or more days a week. Any of the three options clears it.
