Kneel on the machine with your knee supported on the pad and your working leg positioned behind the roller pad. Rest your upper body against the chest pad and grip the handles for stability. Bend your knee to curl your heel toward your glutes against the resistance, squeezing the hamstrings at the top, then slowly extend your leg back to the starting position with controlled movement.
Log your lever kneeling leg curl plate loaded sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
