## How to do the Ab Wheel Half Rollout

1. Kneel with your hips back, the wheel just in front of your knees.
2. Grip the handles firmly, and pull your shoulders down away from your ears.
3. Roll forward until the wheel is directly beneath your shoulders.
4. Pull the wheel back towards your knees, keeping your stomach tight to control the movement.

### Full technique — 6 steps

1. Kneel on a mat with the ab wheel on the floor just in front of your knees.
2. Grip the handles with palms down and sit your hips back behind your knees.
3. Tighten your stomach, squeeze your glutes, and keep your ribs in line with your pelvis.
4. Roll the wheel forward with straight arms as your hips move forward over your knees.
5. Stop when the wheel is directly under your shoulders and your thighs are vertical.
6. Pull the wheel back toward your knees as your hips sit back to the start.

## Common mistakes

- Letting the lower back arch
- Shrugging shoulders toward ears
- Yanking back with momentum
- Bending the elbows to move the wheel

## Form cues

- Keep ribs down
- Squeeze glutes hard
- Keep arms straight
- Stop under shoulders

## How much to do

- **Strength**: 3–4 sets of 8–10 reps · rest 1 min 30 s · 2 reps in reserve · lower 3 s, lift 1 s
- **Muscle growth** (good fit): 3–4 sets of 10–15 reps · rest 1 min · 2–3 reps in reserve · lower 2 s, lift 2 s
- **Endurance** (best fit): 2–3 sets of 15–25 reps · rest 45 s · 3–4 reps in reserve · lower 2 s, lift 2 s

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