5 Day Split Workout Plan

A 5 day split (often called a bro split) trains one body part a day: chest on Monday, back on Tuesday, shoulders on Wednesday, arms on Thursday, legs on Friday, weekends off. Each muscle gets one long, focused session a week. It works when you never skip a day; this page shows the full program and the honest trade-off.

Who this program is for

Each day hits one body part with several exercises and enough sets to train it for the whole week. Chest day also works your triceps, back day your biceps, so arms get extra work.

This is for you if

  • You've trained for at least a few months and know the main lifts.
  • You can train 5 days a week, every week, without skipping.
  • You like to focus on one body part and feel it work.
  • You train at a gym, or at home with a backpack, bands and a pull-up bar.

Not for you if

  • You have pain or an injury: see a doctor or physical therapist first.
  • Your schedule changes a lot: a missed day here means that muscle waits two weeks. Take Upper / Lower instead.

Your week

Keep the order. Weekends off. If you miss a day, do it on Saturday rather than skipping it.

Direct hard sets per week. Chest and shoulder presses add triceps work, back day adds biceps work.

The honest trade-off

A split trains each muscle hard once a week. When studies matched the weekly sets, split and full-body routines built the same muscle and strength. But one study in trained men found that training each muscle 3 times a week grew the arms more than a split, and an earlier meta-analysis favoured twice a week over once. So the split works, as long as you do all the sets and never skip a day. If you can't promise that, Upper / Lower is the safer choice.

Study: Efficacy of Split Versus Full-Body Resistance Training on Strength and Muscle Growth (2024). Ramos-Campo DJ et al., J Strength Cond Res, PMID 38595233. 14 studies, 392 people: split and full-body routines gave the same strength and muscle gains when weekly volume was equal.

Study: How many times per week should a muscle be trained to maximize muscle hypertrophy? (2019). Schoenfeld BJ et al., J Sports Sci, PMID 30558493. 25 studies: with the same weekly sets, training a muscle 1, 2 or 3+ times a week gave similar growth.

Study: Influence of Resistance Training Frequency on Muscular Adaptations in Well-Trained Men (2015). Schoenfeld BJ et al., J Strength Cond Res, PMID 25932981. 20 trained men, 8 weeks: a 3-day total-body routine grew the elbow flexors more than a 1-day-per-muscle split; strength gains were similar.

Study: Effects of Resistance Training Frequency on Measures of Muscle Hypertrophy (2016). Schoenfeld BJ et al., Sports Med, PMID 27102172. Earlier meta-analysis: training a muscle twice a week beat once a week (effect size 0.49 vs 0.30).

How to run it

Warm up · about 10 minutes

  1. Get warm, 3–5 min: brisk walk, bike or jump rope until you're breathing a little harder.
  2. Move the joints, 3 min. Upper days: 10 arm circles each way, 15 band pull-aparts, 10 incline push-ups. Lower days: 10 leg swings per leg, 10 bodyweight squats, 10 hip hinges.
  3. Ramp up the first lift: 1 × 10 very light, 1 × 5 at about half your working weight, 1 × 3 at about three quarters.

RIR: how hard each set is

"RIR 1–2" means: stop when you feel you have 1 or 2 clean reps left. RIR 0 means no more reps possible; 4 or more means the weight is too light.

First two weeks: stay at RIR 3 and learn the movements. After that, follow the card. Going all the way to failure isn't needed [Refalo et al. 2024].

Progress: double progression

Keep the same weight until you reach the top of the rep range on every set, at the RIR on the card. Then add the smallest weight step (+2.5 kg / 5 lb on a barbell, the next dumbbell pair, the next pin) and start again at the bottom of the range.

At home: more reps, then more load in the backpack, then a slower descent (3–4 seconds), then a harder version. Adding reps at the same weight worked as well as adding weight [Plotkin et al. 2022].

Deload, stalls and patience

Deload every 6–8 weeks, or when your joints ache or your numbers drop: one easy week, same exercises, half the sets, RIR 3–4. A full week off mid-program didn't cost any muscle in one study; strength gains were a little smaller [Coleman et al. 2024].

Don't compare: on the same 12-week program, biceps size changed from −2% to +59% between people [Hubal et al. 2005]. Compare yourself with last month's log.

The rules of this program, each backed by a study

Six rules shape this program. Each comes with the study behind it; the exercise-specific studies are on the cards above.

  1. Hard sets build muscle

    The more hard sets a muscle gets each week, the more it grows, up to a point: the gains shrink as you add more. These programs sit in the range where beginners grow well.

    Study: Dose-response relationship between weekly resistance training volume and increases in muscle mass (2017). Schoenfeld BJ et al., J Sports Sci, PMID 27433992.

    Study: The Resistance Training Dose Response: Meta-Regressions Exploring the Effects of Weekly Volume and Frequency (2026). Pelland JC et al., Sports Med, PMID 41343037.

  2. Stop 1–2 reps short of failure

    Growth tends to rise as sets end closer to failure, but going all the way to failure didn't add more muscle than stopping 1–2 reps short.

    Study: Exploring the Dose-Response Relationship Between Estimated Resistance Training Proximity to Failure, Strength Gain, and Muscle Hypertrophy (2024). Robinson ZP et al., Sports Med, PMID 38970765.

    Study: Similar muscle hypertrophy following eight weeks of resistance training to momentary muscular failure or with repetitions-in-reserve (2024). Refalo MC et al., J Sports Sci, PMID 38393985.

    Study: Influence of Resistance Training Proximity-to-Failure on Skeletal Muscle Hypertrophy (2023). Refalo MC et al., Sports Med, PMID 36334240.

  3. Beat your log

    Adding reps at the same weight worked as well as adding weight: both count as progress.

    Study: Progressive overload without progressing load? The effects of load or repetition progression on muscular adaptations (2022). Plotkin D et al., PeerJ, PMID 36199287.

  4. Rest longer on big lifts

    Three minutes between sets beat one minute for strength and for thigh growth in trained men.

    Study: Longer Interset Rest Periods Enhance Muscle Strength and Hypertrophy in Resistance-Trained Men (2016). Schoenfeld BJ et al., J Strength Cond Res, PMID 26605807.

  5. Heavy or light, both work

    Light and heavy loads taken close to failure built similar muscle. Heavy loads built more maximal strength, which is why the big lifts stay in the 6–10 rep range.

    Study: Strength and Hypertrophy Adaptations Between Low- vs. High-Load Resistance Training (2017). Schoenfeld BJ et al., J Strength Cond Res, PMID 28834797.

  6. Train the stretch

    In several studies, exercises that load a muscle in its stretched position grew it more: seated leg curls, overhead triceps extensions, standing calf raises, curls from a straight arm. Most of these studies were done on beginners.

    Study: Greater Hamstrings Muscle Hypertrophy but Similar Damage Protection after Training at Long versus Short Muscle Lengths (2021). Maeo S et al., Med Sci Sports Exerc, PMID 33009197.

Safety

Before you start

This is general fitness information, not medical advice. If you have pain, an injury or a health condition, check with a doctor or physical therapist first, and stop any exercise that hurts.

Under 18? Strength training is safe and worthwhile for teens when it is supervised and taught properly; most reported injuries came from poor technique, wrong loads or no supervision [Faigenbaum & Myer 2010] [Lloyd et al. 2014]. Learn the lifts with a coach, a PE teacher or an adult who knows them. Light weights first, no max lifts, never heavy weights over your head alone.

Skinny Arms? You're Training The Wrong Muscle

Your triceps is about 2.6 times bigger than your biceps, and most skinny guys only do curls. Your upper arm is three muscles: here's how to grow each one, with what the studies actually measured (sources below).

Questions people ask

What is a 5 day split?

One body part a day for five days: chest, back, shoulders, arms, legs, then two rest days. Each muscle is trained hard, directly, once a week. Chest day also works your triceps and back day your biceps, so the arms get extra work.

Is a 5 day split worse than full body?

Not when the weekly sets are equal: in a meta-analysis of 14 studies (392 people), split and full-body routines gave the same strength and muscle gains [Ramos-Campo et al. 2024]. But one study in trained men found that training each muscle 3 times a week grew the arms more than a split [Schoenfeld et al. 2015], and an earlier meta-analysis favoured twice a week over once [Schoenfeld et al. 2016]. The split works as long as you do all the sets and never skip a day.

Who should not do a 5 day split?

People whose schedule changes a lot: with a split, a missed day means that muscle waits two weeks. Take the Upper / Lower plan instead. If you have pain or an injury, see a doctor or physical therapist first.

What if I miss a day?

Keep the order and do the missed session on Saturday rather than skipping it.

How long are the sessions?

Chest, shoulders and arms take 45–55 minutes, back 55–65 minutes and legs 65–75 minutes, rest between sets included.

Can I do this program at home?

Yes. Every exercise has a home version that needs a backpack you can load with books or water bottles, two resistance bands, a doorway pull-up bar, a sturdy chair and a step. For example, push-ups replace the bench press and Nordic curls replace the leg curl machine.

What does RIR mean?

Reps in reserve: how many more clean reps you could still do when you stop the set. RIR 1–2 means you stop when you feel you have 1 or 2 reps left. In one 8-week study, stopping 1–2 reps short of failure grew the quads as much as going to failure [Refalo et al. 2024].
