Build Muscle

Classic Five-Day Split

The five-day body-part split people call the bro split, with one thing changed: every muscle group is trained twice a week instead of once.

Five-Day Body-Part Split, Twice-Weekly Frequency

How it runs

Chest and back run twice with different lifts, legs run twice — quad-led and hip-led — and shoulders and arms get their own day.

What you actually train

5 sessions, in order. Every movement links to how to do it.

  1. Chest & Back A

    7 movements

  2. Legs A (Quad-Led)

    7 movements

  3. Shoulders & Arms

    8 movements

  4. Chest & Back B

    7 movements

  5. Legs B (Hip-Led)

    6 movements

Why it works

  • That second exposure is the whole difference. Training a muscle once and leaving it for seven days is what leaves the hamstrings and calves with almost nothing.
  • Hamstrings get eighteen sets a week across two sessions and calves ten — the two that a traditional leg day has no room for.
  • Chest, back and shoulders keep the volume the split is known for, at sixteen to twenty sets.
  • Every set carries an effort target, and load moves by double progression rather than by feel.
  • Five sessions of about an hour, so no single day has to carry a whole body part on its own.

Warm up with two or three ramping sets of the day's first lift. The two rest days are the minimum at this volume rather than a target to beat.

What to expect

Expect five sessions of about an hour, and expect the hamstrings and calves to get the attention a once-a-week leg day has no room for.

Before you start

Before you start, please read this part. Lifting is among the safest and most useful things most people can do, and there is a short list of exceptions worth checking yourself against first.

If you have a heart or lung condition, chest pain or pressure at rest or on effort, dizziness or blackouts, blood pressure or diabetes that is not currently controlled, a hernia, low bone density or osteoporosis, a joint or back problem that is flaring, or you are pregnant or within a year of giving birth, speak to your GP or a physiotherapist before starting and follow their instruction over anything written here.

Stop the set and get advice for chest pain or tightness, breathlessness out of proportion to the effort, dizziness, or a sudden sharp pain in a joint or the back.

Stop it as well for pain, numbness, pins and needles or weakness that travels down an arm or a leg, and get that seen before you load the pattern again. This programme puts a loaded bar on your back and over your chest.

Use a rack with the safety pins set at the depth you squat to, and do not bench alone without them. Nothing here is medical advice.
