Sit on the leg extension machine with your back firmly against the pad and your legs positioned under the padded lever. Grip the side handles for stability and keep your toes pointed slightly inward. Extend your legs by straightening the knees against the resistance until they are nearly fully straight, then slowly lower the weight back to the starting position while maintaining control to emphasize quadriceps activation.
Log your lever leg extension (inward toes) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
