Sit on the seated leg extension machine with your back against the backrest and your legs placed under the padded lever just above the ankles. Grip the side handles for stability and begin with your knees bent. Contract your quadriceps to extend your legs until they are nearly straight, pause briefly at the top, then slowly lower the weight back to the starting position with controlled movement.
Log your lever seated leg extension (version 2) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
