3. Tighten your stomach and keep your elbows straight for the whole set.

5. Continue until your torso is upright and the bar is overhead, arms in line with your torso.

## Common mistakes

- Bending and straightening the elbows
- Using momentum to start reps
- Swinging the bar forward to sit up
- Feet lifting off the floor
- Dropping back without control

## Form cues

- Keep arms straight
- Lift with abs first
- Exhale on the way up
- Keep knees straight
- Arms point to the ceiling

## How much to do

- **Strength**: 3–4 sets of 6–10 reps · rest 1 min 30 s · 2 reps in reserve · lower 2 s, lift 1 s
- **Muscle growth** (good fit): 3–4 sets of 10–15 reps · rest 1 min 15 s · 2–3 reps in reserve · lower 2 s, lift 2 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 45 s · 3–4 reps in reserve · lower 2 s, lift 1 s

Reps in reserve: how many more you could still do when you end the set.
