Seated Hamstring

What it is

This advanced static flexibility exercise uses resistance to deeply stretch your hamstrings. You will actively contract these muscles against an external force, then relax into an extended stretch. It primarily targets your hamstrings, with secondary benefits for your calves.

Technique tips

• Ensure your legs remain straight with knees locked.
• Actively push your torso back using only your hamstrings.
• Breathe deeply throughout both the contraction and stretch phases.
• Fully relax your muscles during the passive stretch segment.
• Communicate clearly with your partner for optimal stretch depth.
• Perform this stretch slowly and with controlled movements.

How to track your progress

Log the hold time of each set. Straddly keeps your best hold for this exercise and tells you when you beat it, so a two-second gain does not go unnoticed.
