Week by week

Bar height is the week's planned working intensity — a percentage of your one-rep max for lifting, of your benchmark pace for conditioning.

  • Build — Volume rises, loads moderate
  • Load — Fewer reps, heavier bars
  • Peak — Heaviest, lowest volume
  • Test — Measure, then plan the next block

Conditioning you can measure. Engine Build starts with a benchmark row and bike test, paces every interval from it, and repeats the test in week six so you can see exactly what changed. Pairs well with a Strength Block.

  • 2,000 m row and 10-minute bike benchmark
  • Every interval paced from your own numbers
  • Retest in week six
