How to do it
- Hang from a pull-up bar using a pronated grip. Your arms and legs should be extended. This will be your starting position.
- Begin by quickly raising one knee as high as you can. Do not swing your body or your legs. 3
- Immediately reverse the motion, returning that leg to the starting position. Simultaneously raise the opposite knee as high as possible.
- Continue alternating between legs until the set is complete.
Common mistakes
- ✗ Sprinting at full speed without a warm-up.
Why it hurts: Hamstrings are most often strained during maximal sprinting, and cold muscles are less tolerant.
✓ Instead: Warm up with easy running, drills and 3–4 build-up runs before any all-out effort.
- ✗ Over-striding with the foot landing far in front.
Why it hurts: The hamstring is loaded while stretched, which is the typical strain mechanism.
✓ Instead: Land with the foot under the hips and think of pushing the ground back, not reaching forward.
