Sets & reps by goal

GoalSets × repsLoadRest
Strength3–5 × 3–5Heavy (~85%+)2–3 min
Hypertrophy3–4 × 8–12Moderate (~65–75%)60–90 s
Endurance2–3 × 15–20Lighter (~50–60%)30–45 s

As a mobility drill, hold each position for 20–40 seconds (or move slowly for reps) rather than training it to a heavy load.

Form tips

  • Keep the knees tracking in line with the toes and push the whole foot into the floor.
  • Own the largest range you can control with clean form before you chase extra reps.
  • Ease in until you feel mild tension, never pain, and breathe out as you sink a little deeper.
  • Warm up the pattern with a couple of lighter, submaximal sets before your working sets.

Common mistakes

  • Letting the knees cave inward as you push out of the bottom.
  • Cutting the range short to squeeze out extra reps instead of owning each full one.
  • Bouncing into the stretch instead of holding it steadily.
