UNKNOWN — no additional common error is recorded in the biomechanics dataset.

Programming by goal

Goal	Sets × reps	Effort cap	Tempo
Strength	3 × 3-6	RPE ≤ 9	2-0-X-0
Muscle growth	3 × 8-12	RPE ≤ 8	3-1-1-0
Endurance	3 × 15-25	RPE ≤ 7	2-0-2-0

Engine defaults for one exercise. Adjust load so every rep stays within the listed effort cap.

Equipment context

Bodyweight exercises need no equipment, but progression depends on leverage and position rather than added load.
