Seated Hamstring Stretch: Stretch the back of your thigh.

Straighten one leg, place your other foot against the inside of that leg, then slowly lean toward the straight leg, folding from your hips, to stretch the back of your thigh.

How to fix it

  1. Straighten one leg and place your other foot against the inside of that leg.
  2. Slowly lean toward your straight leg.
  3. As you lean, fold forward from your hips.
Caution Lean only until you feel a pull, and do not push into pain.

The app guides each stretch for 30 seconds at a time

When you add a stretch to your routine, the app guides you through 30 seconds on each side, one side at a time, and you can adjust the time yourself.

Where do you place the bent leg's foot?

It varies by source. Some sources say to place the sole of the bent leg against the inner thigh of the straight leg, and others say to place it at the knee of the straight leg. Either way, keep one leg straight and place the sole of the bent leg against the inside of the straight leg.
