PRx Knee Keeper

The PRx Knee Keeper is an attachment that works with the PRx Axis Pad to help you perform better seated pull movements, like lat pulldowns. It's made in the USA and crafted for comfort and durability.

A black vinyl pad provides comfort and support, and a durable black powder coat resists wear. UHMW (ultra-high molecular weight polyethylene) protects against wear and tear, and a 4-hole design lets athletes of all sizes adjust it precisely. The 2-pin attachment makes adjustments quick, so you keep your momentum. It also doubles as a foot holder for crunches and as a backrest with the PRx Leg Curl/Extension attachment.

Specs:

• Product weight: 13 lb

Not compatible with the PRx Elite or Prime pulley systems for lat pulldowns.

Why use a knee keeper? Holding your knees down during pulldowns keeps your body from lifting as the weight gets heavy. As a result, your lats do the work, not your momentum. For lacrosse players, strong lats help power shots and stabilize the shoulders.

How to set it up: first, pin it to your upright above the Axis Pad. Next, adjust it so your thighs are snug under the pad. Finally, grab the bar and pull.

Pair it with the PRx Axis Pad and store it on Profile Knee Keeper storage.
