PRO 2 LEG EXTENSION (PSLE) Muscles Exercised – Quadriceps
Setup
Adjust the back pad to align with the machine pivot, as indicated by the red
axis of rotation decal, with the knee joints. Adjust the lower leg pad to a
comfortable position above the ankle. Using the adjustment knob located on
the machine cam (available on Pro 2 SE only), adjust the start position to the
desired range of motion. Check the weight stack to ensure appropriate
resistance. Grip the handles located on the sides of the seat. Body is
positioned with chest-up, shoulders back and against back pad.
Performing the Exercise
Rotate the thighs so the knees are pointing upwards and with a controlled
motion, extend the legs to near full extension. Return the legs to the start
position, without letting the resistance rest on the stack. Repeat the motion,
while maintaining proper body positioning.
TIP: Position the thighs with the knees pointing upwards and maintain this,
while performing the exercise. This position is safer for the knee joint and
more effective for the Quadriceps muscles.
