How to do the Bottoms Up
Begin by lying on your back on the ground. Your legs should be straight and your arms at your side. This will be your starting position.
To perform the movement, tuck the knees toward your chest by flexing the hips and knees. Following this, extend your legs directly above you so that they are perpendicular to the ground. Rotate and elevate your pelvis to raise your glutes from the floor.
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).
