Done from the edge of a chair, this stretch needs no floor space or kneeling, which makes it the easiest option in this group to use at a desk or between sets. Extending one leg at a time lets you compare tightness between sides; lean forward slowly from the hips and stop as soon as the thigh registers the stretch.
How to do the Seated Single Leg Extension Stretch
- Sit on the edge of a chair with your back straight and feet flat on the ground.
- Extend one leg straight out in front of you, keeping your heel on the ground.
- Lean forward slightly, feeling a stretch in your quadriceps.
- Hold this position for 20-30 seconds.
- Switch legs and repeat the stretch.
Tip: Hold each position for 20 to 45 seconds and breathe out slowly to sink a little deeper.
Muscles worked
Primary
Quads · Legs
The quads lengthen as the knee bends and the hip extends, and you should feel the pull along the front of the thigh.
Secondary
Common mistakes
- Bouncing in the stretch — hold a steady position rather than pulsing, and let the muscle relax into the range over 20 to 30 seconds.
- Arching the lower back — on quad and hip flexor stretches tuck the pelvis and squeeze the glute of the stretched side so the stretch lands on the front of the hip, not the spine.
- Holding the breath — breathe slowly and steadily so the muscle can relax.
- Going for pain — a stretch should feel like a firm pull, never a sharp pain; back off until it does.
Where it fits in a workout
Stretches go at the end of a session or on rest days, not right before heavy lifting. Pair a quad stretch with a hamstring stretch to cover both sides of the leg.
