Kneeling hip flexor
Played on both sides, one round each; the app tells you when to turn round. Under a minute a side.
How to do it
- Kneel on one knee, front foot flat
- Kneeling leg nearest the phone
- Tuck your tailbone, hips forward
What it is for
The app files this stretch under:
- Stiff hips
- Tight quads
- Tight glutes
Where the phone goes
Phone on the floor, not angled up, about 70° to your side and 6 ft away. The phone sits off to one side of you, so the camera sees the leg and the trunk in profile. Every stretch shows you this picture before the clock starts, and talks you through it, because you are across the room by then.
In the game
The gap in the kelp sits at the depth you settle on yourself, and staying near that depth is the whole skill. Points come from how steadily you hold the spot you picked. Depth earns nothing, and going deeper than you can comfortably hold is the thing the app is built to avoid asking of you.
That is also what the research says: a gentle hold gains as much range over the weeks as a hard one. What regular stretching does, measured.
