Step by step instructions
Load 30 to 50 pounds on a seated leg press and sit with feet hip-width apart on the plate. Adjust your position so knees are bent 90 degrees. Release the brake, then extend legs. Lift left foot (or shift it down so it’s barely touching the plate) and slowly bend right knee 90 degrees.
Place left foot next to right again and extend legs to return to starting position. Repeat, this time lifting right foot. Continue, alternating feet each rep.
