What it is
This seated stretch helps improve flexibility in your hamstrings. You bend forward to hug your thighs from underneath, bringing your chest towards your knees to also engage your lower back and middle back.
Technique tips
- Keep your legs fully extended and knees together.
- Actively pull your chest towards your knees to deepen the stretch.
- Breathe slowly and deeply to help relax into the hold.
- Gently round your middle back for an added upper back stretch.
- Avoid bouncing; maintain a steady, static hold.
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.
