## How to do the Alternating Machine Decline Chest Press

1. Adjust the seat so the handles line up with your lower chest.
2. Sit upright against the pad, feet flat on the floor, and grip firmly.
3. Press one handle forward and slightly down until your arm is extended.
4. Lower it slowly, then press with the other arm.

### Full technique — 6 steps

1. Adjust the seat so the handles start around lower-chest level when you sit down.
2. Sit tall with your head and upper back against the pad and feet flat.
3. Grip the handles firmly and set your shoulders down and back before pressing.
4. Press one handle forward and slightly down until that arm is extended, keeping the other handle at your chest.
5. Lower the handle under control until it returns near the starting position.
6. Press with the other arm, alternating arms each rep.

## Common mistakes

- Seat set too high or low
- Shoulders rolling forward at extension
- Twisting the torso to finish reps
- Partial reps from shortened range
- Letting the resting arm drift forward
- Bouncing into the next rep

## Form cues

- Don't roll shoulders forward
- Shoulders stay on pad
- Hold the other handle still
- One arm at a time
- Press through full reach

## How much to do

- **Strength** (good fit): 3–4 sets of 5–8 reps · rest 2 min · 2 reps in reserve · lower 2 s, lift 1 s
- **Muscle growth** (best fit): 3–4 sets of 8–12 reps · rest 1 min 30 s · 2 reps in reserve · lower 2 s, lift 1 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 1 min · 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.
