M7i WHEELCHAIR-ACCESSIBLE TOTAL BODY TRAINER
BIOMECHANICAL POSITION
Proper biomechanical positioning is necessary for a safe, comfortable, and effective workout. The following steps
should be taken prior to every workout. Figure 9 "Biomechanical Positioning" shown below demonstrates proper
positioning throughout your workout:
1. Position your wheelchair so your feet are directly over the M7i Base Plate.
2. Place your feet onto the Footpads. Extend one Footpad to the furthest position. Check to ensure your knee has
a slight bend and that your lower thigh makes minimum contact with the seat. Reposition your wheelchair as
needed for proper reach and comfort.
3. Grab one Handle and extend it to the furthest position. With your back against the wheelchair backrest, check
to ensure your elbow has a slight bend with the Handle at the furthest point. Adjust the Handle reach as needed
for proper reach and comfort.
4. Once proper leg and arm reach are attained, lock the wheelchair brakes (powered mobility devices should be
turned off). Set the Recoiler Safety Straps (refer to page 11 "Safety Recoiler Straps" section).
HANDS AND ARMS
Ensure a firm grasp throughout the exercise and
that your elbows keep a slight bend at full extension.
Keep your hands in front of your chest. Adjustable
Handles allow users of varied heights to exercise
comfortably. Swivel Handles allow wrists/shoulders
to rotate naturally and freely.
LEGS
At full leg extension, ensure that
your knee keeps a slight bend
and that your lower thigh
makes minimum contact with
the seat. Keep your legs in
line with the Footpads.
The legs should not be
bowed out or inward.
FEET
Place your feet on the Footpads with heels resting
against the Footpad rear wall. Foot Straps provide
secure footing during exercise. NOTE: Ensure Foot
Straps are snug to fit, without causing any discomfort.
Shown with optional Leg Stabilizers and Adaptive Wrist Straps (Part Number 520800), available for individuals with limited control
of legs or arms. Consult with your physician to determine if these items are right for you.
HEAD AND NECK
Keep your head and neck in alignment with your body.
Your eyes and ears should be on the same horizontal
plane and parallel with the floor.
Figure 9. Biomechanical Positioning
BACK AND SHOULDERS
Your back must be fully supported by your wheelchair
backrest at all times. Adjust any backrest support,
cushion, or pillow for comfort. Avoid sitting at the edge
of your seat. Maintain the natural curves of the spine and
avoid leaning forward or arching your back to achieve
proper posture.
