Leg Curl / Extension Dimensions & Clearance Requirements

Total floor space required

5' 3" (1.6 m) x 8' 6" (2.6 m)

The leg curl / extension itself measures 3' 3" (1.0 m) x 4' 11" (1.5 m), but it cannot be used in that space alone. The figure above includes the clearance required on every side.

Clearance, side by side

front: 2' 7" (0.8 m): Working space for the user — entry, exit, and the movement itself.
back: 1' (0.3 m): Wall standoff for cables, airflow, and maintenance access.
left: 1' (0.3 m): Side space for spotters, loading plates, and passing traffic.
right: 1' (0.3 m): Side space for spotters, loading plates, and passing traffic.
