Equipment machine
Difficulty beginner TARGET AREA
Muscles worked THE MOVEMENT
How to perform Adjust the seat and shin pad so the machine pivot lines up comfortably with the knee. Sit back against the pad and hold the handles for stability. Extend the knee until the leg is straight or near straight without kicking the weight. Lower under control until the quad is lengthened again. Adjust the machine so the knee lines up comfortably with the pivot. Keep the hips and torso against the pad while the lower leg moves. Control both the extension and return instead of letting the stack drop. STAY SHARP
Common mistakes Using momentum to kick the weight up. Letting the hips lift off the seat. Using a setup that places the pad or machine pivot in an uncomfortable position. IRONYOU RANK CALCULATOR
