How to perform
Step by step, every rep
01
Adjust the seat
Handles should line up around mid chest with shoulders down.
02
Open with control
Let arms travel back until you feel a chest stretch, not shoulder pain.
03
Bring arms together
Squeeze the chest as handles meet in front of you.
04
Keep tension
Do not let the weight stack slam between reps.
Common mistakes
Avoid these
✕
Overstretching
The shoulder joint gets stressed before the chest benefits more. Fix: Stop at a strong chest stretch with no pinch.
✕
Bending and straightening elbows
It turns into a weird press. Fix: Keep the same soft elbow bend throughout.
✕
Using too much load
Momentum beats the chest squeeze. Fix: Pause in the contracted position every rep.

How to program it
Sets, reps, rest
| Goal | Sets | Reps | Rest | Load |
|---|---|---|---|---|
| Build Strength | 3-4 | 6-8 | 90-120s | Heavy enough to need focus, light enough to control. |
| Build Muscle | 3-4 | 8-15 | 60-90s | Moderate. Last 2 reps should burn without breaking form. |
| Build Endurance | 2-3 | 15-25 | 45-60s | Lighter. Smooth tempo and constant tension. |
