Single-leg Head Touch Knee Forward Fold
The single-leg head touch knee forward fold is a bodyweight stretching exercise targeting the hamstrings. Performed standing, it involves a deep hip hinge toward one extended leg, progressively deepening the stretch in the hamstrings and calf while challenging balance and lower back flexibility.
How to do it
- Stand tall with your feet together and your arms relaxed by your sides.
- Shift your weight onto one foot and extend the opposite leg slightly forward, keeping it straight.
- Hinge forward at the hips, reaching your hands toward the extended foot while keeping your back flat.
- Continue folding until your head moves toward the knee of the extended leg.
- Hold the bottom position for 15-20 seconds, then slowly return to standing.
- Repeat on the opposite side for the desired number of repetitions.
Form cues
- Keep your front leg straight but not locked.
- Hinge from your hips, not your lower back.
- Keep your chest open as you fold forward.
- Breathe deeply and relax into the stretch.
Breathing: Inhale as you stand tall and prepare to hinge, then exhale slowly as you fold forward and hold the stretch.
Common mistakes
- Rounding the lower back because this reduces the stretch on the target hamstring and strains your spine.
- Bending the front knee too much because this shifts the work away from the hamstring.
- Holding your breath because this causes your muscles to tense up against the stretch.
Muscles worked

What if I cannot reach my knee with my head?
That is completely normal for beginners. Only fold as far as your flexibility allows without rounding your lower back.
How often should I do this stretch?
You can safely practice this stretch daily or after your workouts to gradually improve hamstring flexibility.
Should it hurt?
You should feel a gentle pull in the back of your leg, never sharp or shooting pain. Ease off immediately if you feel pain.
