Clamshell – how to do it right
Lying on your side, feet together, open your top knee.
This is how Stickfreed, our glowing stick figure, shows you the exercise on your TV – here the start, middle and end position. In the app he turns slowly so you can see everything.
How to do it
- On your side, knees bent, feet together.
- Open your top knee – feet stay together.
- Hips stay still – don’t roll back.
- Close slowly and switch sides.
How long?
40–45 seconds at a steady pace: slow on the way down, strong on the way up. 2–4 rounds. Then switch sides – BLOX tells you when.
If something niggles
Don’t fancy the floor? Then do Glute bridge instead – BLOX swaps it automatically if you mention it at the start. Stop if it hurts; if you have complaints or pre-existing conditions, check with a doctor or physio first.
In BLOX
Part of these blocks: Mat: hips & core. BLOX builds your workout from them – based on your time, energy and how you feel today.
