3x3" Leg Curl & Extension Seat Attachment | Fitness Canada™

The 3x3" Leg Curl & Extension Seat Attachment by Fitness Canada™ is a compact, space-saving gym solution that transforms your existing power rack into a dual-function lower-body commercial machine. Designed to mount directly to heavy-duty uprights, it gives you full targeted leg-day capability—isolating your quadriceps and hamstrings—without requiring a massive standalone footplate machine.

This plate-loaded attachment delivers dual-action functionality:

• Seated Leg Extensions: Sit on the integrated seat facing away from the rack, place your shins behind the lower roller pad, and extend for complete quadricep isolation.
• Prone or Standing Leg Curls: Lay face-down on a flat bench or stand facing the unit, placing the back of your ankles against the pad to curl toward your glutes for dedicated hamstring development.

Both the straight-flat seat position and the leg extension/curl arm feature 6 position-adjustment holes, ensuring accurate alignment for different leg lengths and ranges of motion. The Olympic (2") weight sleeve is designed to load up to three 55 lb competition bumper plates (165 lbs+) or even more compact cast iron plates for progressive overload.

Note: Power rack uprights and weight plates are sold separately. Designed strictly for true 3" x 3" power racks with 1" pin holes.
