How to perform On Your Side Quad Stretch

  1. Start off by lying on your right side, with your right knee bent at a 90-degree angle resting on the floor in front of you (this stabilizes the torso).
  2. Bend your left knee behind you and hold your left foot with your left hand. To stretch your hip flexor, press your left hip forward as you push your left foot back into your hand. Switch sides.

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.
  • Control the lowering phase — a 2–3 second descent builds more than dropping the weight.

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.
