How to do the Cocoons
Begin by lying on your back on the ground. Your legs should be straight and your arms extended behind your head. This will be your starting position.
To perform the movement, tuck the knees toward your chest, rotating your pelvis to lift your glutes from the floor. As you do so, flex the spine, bringing your arms back over your head to perform a simultaneous crunch motion.
After a brief pause, return to the starting position.
Sets and reps
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Muscle growth | 3–4 | 6–15 | 1.5 min |
| Muscular endurance | 2–3 | 15–20 | 1 min |
When you hit the top of the rep range on every set, add a rep or a harder variation next session.
Starting points from training research. Stop each set 1–3 reps short of failure.
Muscles worked
Primary
The abs flex your spine and stop it from arching. Mix crunching moves (crunches, leg raises) with anti-extension work (planks, rollouts).
