Keiser m3 TBT User Manual - Tbt Fitting
SEAT POST HEIGHT POSITIONING
• Stand beside the TBT, close to and beside the saddle.
• Position the seat so that the top of the saddle is level with your iliac crest (hip), then
re-tighten the T-Handle after adjustment.
• Sit on the saddle with the balls of each foot over the center of the pedals.
• Begin to pedal very slowly. There should be a 5-15 degree bend in the knee as it
extends down into the six o’clock position.
WARNING: If your hips are rocking back and forth in the saddle with each pedal stroke,
the seat position may be too high. Uneven rocking from side to side may result in hip or
back injuries.
WARNING: Maximum weight of the rider shall not exceed 300lbs /136kg.
TBT FITTING
WARNING: If a participant’s knees are bowed outward (beyond their normal ergonomic
position), the seat may be too low. If the knees are too flexed, unwanted stress is placed
on the knee caps. The knee should never be in a locked-out (overextended) position.
WARNING: This adjustment shall not exceed the mark “STOP” indicating minimum
insertion depth for safe operation. See inset image, below right.
POSTURE AND BODY POSITION
We suggest that you keep your back upright during any exercise on the TBT. Avoid
leaning your body forward or backward while exercising.
FORE AND AFT (FORWARD AND BACKWARD) SEAT POSITIONING
• With the seat in the correct height position. Keep both hands on the handles while
checking fore and aft positioning.
• Sitting on the saddle with your feet
on the pedals in the three-o’clock
and nine-o’clock position (left or right
crank arm in line with the link). When
looking down, the front of your knee
cap (patella) should be in line with the
middle of the pedal at the point where
the crank arm meets the pedal.
• If when looking down, you can’t see
your toes, the seat should be shifted
back. Similarly, if you can see your
entire foot, the seat should be shifted
forward. Adjust, then and re-check the
knee cap alignment.
