German Body Comp is Charles Poliquin's method for changing body composition with the barbell rather than the treadmill. Whole-body sessions of supersetted compound lifts, on strict tempos, with rest capped at 60 seconds — and shrinking.
The mechanism is hormonal: incomplete rest on big-muscle supersets drives blood lactate high, and lactate drives growth hormone — the lever that mobilises fat while the loading itself defends your muscle. You finish sessions breathing like conditioning; you adapt like lifting.
It is not circuit training. The loads are real, the tempos are strict, and the rests are measured to the second. Take away any of the three and it stops being GBC.
How it works
- 1Pair non-competing compound lifts — lower body with upper body — into supersets.
- 2Load them on strict tempos: five-second eccentrics are standard in accumulation.
- 3Rest 60 seconds or less, always. The rest cap is the intensity dial.
- 4Wave the sets and reps down as the weeks progress; rotate lifts to a close variation between blocks.
In the app
- —BODY COMP is PRE SZN's GBC program — the founder's own: two four-week blocks, descending waves, the six-workout rotation rule, sled and rope finishers.
- —The app times every rest to the second and prints the tempo on every lift — the two things a GBC session cannot survive without.
- —Heart-rate kinetics from the watch show you what the incomplete rest is actually doing.

Programs that run it
Questions
Is GBC cardio or lifting?
Lifting, structured so your heart never gets a break. The stimulus is loaded compound movement; the density makes it condition. It replaces neither maximal strength work nor easy aerobic work — it occupies the space between.
How fast does GBC change body composition?
Poliquin built it for visible change inside a block. PRE SZN's BODY COMP runs eight weeks; with food in order, that is long enough for the mirror to notice.
Can beginners run GBC?
Learn the lifts first — GBC on real loads with strict tempos and 60-second rests is an advanced ask. Run Academy: Foundations or Strength Foundations before it.
