How to perform
Step by step, every rep
01
Set your stance
Place feet shoulder width on the platform. Start mid-platform, then adjust for comfort and knee tracking.
02
Brace into the pad
Keep back and hips against the support. Unlock the handles only when you are stable.
03
Lower with knees tracking
Descend under control as knees travel over toes. Keep heels planted.
04
Drive up
Push through the whole foot and stop just short of slamming the knees into lockout.
Common mistakes
Avoid these
✕
Feet too high
Glutes take over and quad tension drops. Fix: Move feet lower until knees can travel comfortably.
✕
Bouncing at the bottom
Knees and hips take the impact. Fix: Pause lightly and drive up with control.
✕
Locking out aggressively
Tension leaves the quads and joints take the finish. Fix: Finish tall but keep a tiny knee bend.

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. |
