Best Powerbuilding Split: 4-Day and 5-Day Weekly Plans

The best powerbuilding split is the one that gives each big lift two good exposures a week and still leaves room for muscle-building work. For most lifters that means four days. If you have more time, a five-day split adds volume where you want size.

This guide shows you how to choose between them, with full sample weeks you can copy.

What a powerbuilding split has to do

A powerbuilding split serves two goals. It must train the squat, bench press and deadlift often enough to drive strength. It must also give every major muscle enough hard sets to grow.

That creates three requirements:

• Two exposures per main lift. One heavy day and one lighter or variation day.
• Enough weekly volume per muscle. Spread over at least two sessions so no single day runs too long.
• Recovery between heavy days. Keep heavy squats and heavy deadlifts at least 48 hours apart.

How often you should train each muscle

Frequency matters less than most lifters think, as long as total volume is in place. A meta-analysis of 25 studies on training frequency and muscle growth found no meaningful difference when volume was equated.

"Thus, for a given training volume, individuals can choose a weekly frequency per muscle groups based on personal preference."

Schoenfeld BJ, Grgic J, Krieger J, Journal of Sports Sciences, 2019. PubMed 30558493

Strength is a little different. A 2026 set of meta-regressions pooled 67 studies and 2,058 participants, 79.1% of them male. The authors reported a 100% posterior probability that strength gains rise with frequency, with diminishing returns (Pelland et al., 2026). Muscle growth showed no clear frequency effect in the same analysis.

An earlier meta-analysis of 22 studies reached a similar practical point. Higher frequency helped strength mainly because it allowed more weekly volume (Grgic et al., 2018).

So the rule for powerbuilding is simple. Train each powerlift two or more times a week for strength. Spread muscle volume over whatever schedule you can sustain.

The 4-day upper/lower powerbuilding split

This is the default choice. It fits the American College of Sports Medicine guidance of 3 to 4 days per week for intermediate lifters. It also hits every main lift twice (ACSM, 2009).

Monday, Lower heavy

• Back squat: 5 x 3 at 82.5% to 87.5% of 1RM
• Romanian deadlift: 3 x 8 at RPE 7 to 8
• Walking lunge: 3 x 10 per leg at RPE 8
• Leg curl: 3 x 10 to 12 at RPE 9
• Calf raise: 3 x 12 to 15

Tuesday, Upper heavy

• Bench press: 5 x 3 to 4 at 80% to 87.5%
• Barbell row: 4 x 6 to 8 at RPE 8
• Seated dumbbell press: 3 x 8 to 10 at RPE 8
• Lat pulldown: 3 x 10 to 12 at RPE 9
• Triceps pushdown: 3 x 12 at RPE 9

Thursday, Lower volume

• Deadlift: 4 x 3 at 80% to 85%
• Pause squat: 3 x 5 at 70% to 75%
• Leg press: 3 x 10 to 12 at RPE 8 to 9
• Back extension: 3 x 12
• Hanging leg raise: 3 x 10 to 15

Friday, Upper volume

• Close-grip or Larsen bench: 4 x 6 to 8 at 70% to 75%
• Weighted pull-up: 4 x 6 to 8 at RPE 8
• Incline dumbbell press: 3 x 10 to 12 at RPE 8 to 9
• Cable row: 3 x 10 to 12 at RPE 9
• Lateral raise and curl: 3 x 12 to 15 each

Rest days fall on Wednesday and the weekend. Heavy squat and deadlift days sit three days apart.

The 5-day powerbuilding split

Choose five days when you recover well and want more size on specific muscles. ACSM lists 4 to 5 days per week for advanced trainees, so this is a normal step up (ACSM, 2009).

Keep the four days above. Then add a fifth session focused on the muscles you most want to grow.

Saturday, Hypertrophy and weak points

• Chest-supported row: 4 x 10 to 12 at RPE 9
• Dumbbell bench or machine press: 3 x 10 to 12 at RPE 9
• Hack squat or leg extension: 3 x 12 to 15 at RPE 9
• Rear delt fly: 3 x 15
• Curl and overhead triceps extension: 3 x 12 each

Keep the fifth day free of heavy barbell work. Its job is volume, not more fatigue on your main lifts.

Which split should you pick

• Pick 4 days if you are newer to powerbuilding, sleep under 7 hours, or train 60 to 75 minutes per session.
• Pick 5 days if you recover well, enjoy training often, or have a lagging muscle group.
• Avoid 3 days unless your schedule forces it. You can still run full-body sessions, but each day gets long.

How to progress your split

Run main lifts on percentages and step them up through a block. ACSM recommends a 2% to 10% load increase once you can do one or two reps beyond the target (ACSM, 2009). For barbell lifts, the small end of that range works best.

A practical model:

1. Weeks 1 to 3: add 2.5% to each main-lift prescription per week.
2. Week 4: lighter week at about 70% for fewer sets.
3. Accessories: use double progression. Hit the top of the rep range, then add load.

Keep the split stable for at least 8 weeks. Changing days constantly makes progress hard to measure.

Build it in the free builder

Open the program builder and choose four or five training days. Enter your squat, bench and deadlift 1RMs. Lay out the days as shown above, with each main lift set as sets x reps at a percentage and each accessory set as a rep range with an RPE target.
