MODES OF USE
1. ISOMETRIC
• Muscle contraction without movement against a static weight
• How to: choose a xed numbered position for the range limiter under the carriage by pulling the pin and sliding range limiter to
the desired position. Move the weight stack disengagement lever to the “unlocked” position. Switch the carriage lock-out lever to
the “locked” position. Gently slide carriage back until it locks in position.
2. LOADED ISOMETRIC
• Muscle contraction without movement holding resistance from the weight stack at a xed position
• How to: choose a xed numbered position for the range limiter under the carriage by pulling the pin and sliding range limiter to
the desired position. Switch the carriage lock-out lever to the “unlocked” position. Choose the loaded weight at the weight stack
and gently slide carriage back until contacting the range limiter. Hold the weight at the xed position.
3. ISOTONIC
• Muscle contraction through a desired range of motion, with or without limitation of movement, using the weight stack as the
resistance mechanism.
• How to: Pin your desired weight stack resistance and perform exercise through a desired range of motion using slow, controlled
movements.
4. PLYOMETRIC
• Explosive movement training or “jump training”.
• How to: choose your elastic band strength and wrap the band (or bands) through the blue band pegs on the outside of the
frame. Move the weight stack disengagement lever to the “unlocked” position. Perform your plyometric exercise as desired.
• ***CAUTION*** Take note of the range limiting device location. Manufacturer suggests positioning the limiting device in the last
position to reduce the chances of a sudden stop of the carriage during explosive movements.
5. ELASTIC
• A form of isotonic training using bands as the primary form of resistance creating increasing loads as the range of motion
increases.
• How to: choose your elastic band strength and wrap the band (or bands) through the blue band pegs on the outside of the
frame. Move the weight stack disengagement lever to the “unlocked” position. Perform exercise through a desired range of
motion using slow, controlled movements.
6. COMBINED (ELASTIC & WEIGHT STACK)
• Using elastic bands and the weight stack of the machine to produce resistance at the same time.
• How to: choose your elastic band strength and wrap the band (or bands) through the blue band pegs on the outside of the
frame. Move the weight stack disengagement lever to the “locked” position. Pin your desired weight stack resistance. Perform
exercise through a desired range of motion using slow, controlled movements.

INTENDED USE
The intended use of the Matrix MD-S70 Medical Leg Press is to create a
predetermined, dened physical activity level for the patient. The physical activity
level is generated by the user pushing against a stationary foot plate to move the
seat against a chosen resistance. Alternatively, both the foot plate and the seat
may be locked into stationary positions, allowing the user to perform isometric
exercises. This physical activity level can be done in the controlled environment
of a doctor’s oce or a clinician’s lab. The stress intensity of the physical activity
level can be adjusted by adjusting the amount of resistance applied to the chair,
or by the perceived effort as described by the user to the doctor or clinician.
Metabolic System: The medical leg press can be used to inuence the metabolic
system to increase fat-burning, thereby reducing the size of adipose tissue deposits.
Physical Performance Tests: The dened stress intensity of the
physical activity level can be used to perform physical performance
tests on the strength of the user’s leg muscles.
Recovery: Under a doctor’s care, the medical leg press can be used to improve
muscle strength after surgery or injury. The handrails and seat of the medical
leg press can be used for additional safety and stabilization of the patient.
Orthopedic Rehabilitation: Under a doctor’s care, the medical leg
press can be used for orthopedic rehabilitation (e.g. supporting
dened/reduced weight to strengthen the legs of a user).
PROPER USAGE
1. Do not exceed weight limits of the exercise device.
2. If applicable, set safety stops to appropriate height.
3. If applicable, adjust seat pads, leg pads, foot pads, range of motion
adjustment, or any other type of adjustment mechanisms to a comfortable
start position. Make certain that the adjusting mechanism is fully
engaged to prevent unintentional movement and to avoid injury.
4. Sit on bench (if applicable) and get into appropriate position for exercise.
5. Exercise using no more weight than you can safely lift and control.
6. In a controlled manner, perform exercise.
7. Return weight to its fully-supported start position.

ADJUSTMENT POINTS
FOOT PLATFORM STARTING POSITION
1
Grasp handle, squeeze pin, push or pull platform
to desired start position, release pin.
Allows the user to adjust the starting position of
the footplate. The user pulls the pin and slides
the platform closer or further away to achieve
the desired knee exion at the start position.
Foot Rest
3
Grasp center of foot rest, pull out to full extension.
Gives the user a place to rest a foot
while doing 1-legged exercises.
The foot rest is not intended to support the
user’s complete body weight. Do not apply
more than 300 lbs (136 kg) to the foot rest.
Stack Release
4
To release carriage from the weight stack, grasp handle
under seat and rotate to the unlocked position .
This disengages the weight stack from the
carriage allowing the user to perform a body
weight or band resistance only leg press.
1
The seat side handles are intended to aid the user to remain
in the seat while doing the exercise. The handles are not
intended to support the user’s complete body weight. Do not
apply more than 300 lbs (136 kg) of force to the handles.

Foot Platform Adjustment
2
– Therapist Position
To adjust the foot platform forward or back step down on
the adjustment pad, position platform and then release.
Allows the Therapist to adjust the starting position of the
footplate. The therapist steps down on the adjustment
pad, slides the platform closer or further away from
the user to achieve the desired knee exion at the start
position, and then releases the adjustment pad.
*It is easier to do when standing at the
rear of the unit versus the side.

ADJUSTMENT POINTS
Shoulder Pad Adjustment
5
Squeeze handle down and slide shoulder harness
up or down to a comfortable starting position.
Carriage Lock
7
To lock the carriage into a xed position, grasp
handle and rotate to the lockout position.
By sliding the carriage back to the range limiter
position and engaging the carriage lockout, this
allows the user to perform isometric exercises.

Back Pad Adjustment
6
Pull pin, increase or decrease the angle of the back
pad to comfortable start position, release pin.
Allows the user to adjust the starting position of the back
pad. The user pulls the pin and slides the back pad closer
or further away to achieve a comfortable start position.
Range Limiter
8
Pull-pin and slide carriage bumper forward or
backward to limit the carriage range of motion.
