Which of the following would be an incorrect technique for the leg extension exercise?
a. allow the buttocks to leave the seat during the downward movement phase
b. squeeze the quadriceps muscles at the top of the movement
c. keep the thighs, lower legs, and feet parallel to one another
d. lower the pad until the knees are at a 90° angle
e. keep the back flat against the seat throughout the movement
Answer: a. allow the buttocks to leave the seat during the downward movement phase
Allow the buttocks to leave the seat during the downward movement phase is incorrect because not ensuring the five points of contact during any movement that involves a bench or seat is an indication of incorrect technique. The leg extension exercise is designed to increase the size and strength of the quadriceps muscles.
