Leg Exercises

Muscles worked: Although the squat is often

considered a total body exercise, the glutes,

adductors, hamstrings and quads are primary

movers and the spinal erectors are key to

stabilization.

Pulley position: Low pulley.

Starting position:

• Remove the back support and place the seat in

free sliding position.

• Use the bar harness to adjust strap length

allowing tension at the appropriate depth. This

will require experimentation. Increase depth

slowly according to your ability, knee conditions,

etc. Most orthopedists recommend that healthy

knees not go any lower than a 90 degree angle

(between the thigh and calf) when using extra

resistance. Many people go lower for their goals,

but this dramatically increases the risk to the

knee cartilage and increases the probability of

degenerative/arthritic changes.

• Sit on the seat facing the Power Rods

®

and

position the bar on the traps (across the

shoulders, not on the neck). Maintain a grip on

each side of the bar.

• Flatten your back, keep your chest up and

position your feet in line with the cable/pulley.

• Place your feet wider than hip width and point

your toes outward slightly. Direct the thighs to

the same outward angle as the feet.

Motion:

• While keeping your back straight, tighten your

abdominals and move to a standing position.

• Keep the pressure through the middle of the

arches/feet, not through the toes or heels.

• Using control, slowly squat down by sticking

the hips out as the knees start to bend. Keep the

chest up and back flat as the hips continue to

move backward.

• Lower to approximately 90 degrees at the knees

(unless otherwise determined).

• Do not return to the seat until the end of the last

repetition.

Key points:

• Keep knees pointed the same direction as the

toes.

• Keep the head/neck in line with the trunk.

• Pay close attention to all alignment and

stabilization issues on every part of each and

every repetition!

• Never attempt to exercise with more resistance

than you are physically able to handle. And

be sure to properly place the bar in a secure

location on your shoulders.

The Squat

Knee Extension, Hip Extension, Ankle Plantarflexion

Muscles worked: This exercise develops

overall lower body pushing strength, primarily

emphasizing your knee extensors on the front

of your thighs (quadriceps), your hip extensors

muscles on your rear (gluteus maximus), as well

as on your inner thighs (adductor muscle groups).

Pulley position: Narrow.

Starting position:

• Remove the bench and unlock the rowing seat.

• Sit on the seat facing the Power Rods

®

with the

leg press belt attached and adjusted. Support

your feet on the upright pulley frame or foot

rests as shown. The belt should be placed

around the pelvis, NOT the low back/spine.

• Lift your chest, tighten your abs and maintain a

very slight arch in your lower back.

• Slowly straighten your legs, but do not lock your

knees.

• You may rest your hands around the sides of the

belt, on the sides of the seat, or you may fold

your arms across your chest, whichever is more

comfortable.

Motion:

• Bend your knees and hips slowly allowing

yourself to slide toward the Power Rods

®

.

• Limit your slide to a position that allows you

to still maintain good spinal posture, with your

chest lifted, abs tight and a slight arch in your

lower back.

• Slowly return to the starting position.

Key points:

• Generate the force for the leg press by mentally

directing your pushing/pressing effort through

the lower leg and squarely into the frame of the

machine. In other words, push in the direction

the calf bone is pointing throughout the motion,

rather than just pushing your body backward.

This will decrease the shearing forces at the

knee.

• Keep your knees pointed in the same direction

as your feet. DO NOT let the knees travel

inward/closer during the motion.

• Keep your spine in good posture.

• Straighten but do not “lock out” your knees.

Keep your quads tightened throughout the entire

motion.

• Do not use momentum. MOVE SLOWLY! Do not

“launch” yourself when you straighten your

knees.
