A favorite of power-lifters and bodybuilders combining ascending then descending loading — reps fall as load rises, then reverse.

Detail

The pyramid (triangle) system is a favorite of power-lifters and bodybuilders. It is a combination of the two previous systems — the light-to-heavy (ascending) and heavy-to-light (descending) systems — incorporating both within the same exercise.

A handwritten load/rep progression appears beside this system in the source, recording an ascending sequence of increasing intensity with falling reps:

  • (8) 1RM
  • (6) 85%1
  • (4) 90%(1)
  • (2) 95%(1)
  • (1) 4(1RM)

The pyramid is listed among the popular order-of-exercise systems for the hypertrophy/bodybuilding program, alongside the split routine and GNL rotational systems.

Key facts

  • Combines ascending (light-to-heavy) and descending (heavy-to-light) loading.
  • Reps decrease as load increases toward the apex, then reverse on the descent.
  • Handwritten progression (uncertain): 8 reps → 6 @ 85% → 4 @ 90% → 2 @ 95% → 1 @ 1RM.
  • Popular with power-lifters and bodybuilders.

Connections

  • light-to-heavy — the ascending half of the pyramid.
  • heavy-to-light — the descending half of the pyramid.
  • split-routine, gnl-rotational — co-listed popular bodybuilding ordering systems.
  • intensity, repetition — varied inversely up and down the pyramid.
