About PRx Knee Keeper
Seated pulls and leg‑focused cable work feel better when you’re locked in. The PRx Knee Keeper pairs with the PRx Axis Pad® to secure your legs for strong, repeatable reps. A compact, American‑made design with quick adjustments keeps your session moving.
Stay planted for stronger pulls
If your knees lift during rows or pulldowns, you lose leverage and strain your lower back. The Knee Keeper fixes that. The 5" pad presses comfortably across the thighs to keep you down and braced. Your torso stays tight, your line of pull stays clean, and every rep feels consistent. That stability helps you load the back safely and focus on the muscles you’re training—not on fighting the setup.
- Comfortable 5" diameter pad, 9" length
- Locks legs for seated pulls and row variations
- Smooth, supportive vinyl wrap
Fast adjustments for any lifter
You don’t need a long reset between movements. With a two‑pin system and a 4‑hole pattern, you can dial pad height quickly to match your leg length. The standalone design also works as a foot holder for crunches or as a backrest when paired with Axis Pad® leg curl/extension work. One attachment, many uses, zero wasted time.
- Two‑pin attachment for quick changes
- Four height positions for precise fit
- Doubles as a foot holder or backrest
