- To increase the challenge when using your AB-DOer® Twist™ machine, condition yourself to maintain constant motion without hesitation.
- You can also increase the challenge by positioning the Contouring Arm Bars over your shoulders; then you can alternate the Contouring Arm Bars under-your-arms.
- Performing your motions in a coordinated fashion will provide a greater degree of skill improvement and muscle control, and you’ll burn more fat, quicker!
- Feel free to add resistance by inserting any one of the Resistance Rods, or by turning the Swivel-Action Seat’s resistance dial.
- If you fatigue in any position simply:
- Change to another movement, or
- Slow down the speed, or
- Reduce the range-of-motion, or
- Return the Arm Bar to underneath your arms, or
- Lower the resistance on the Swivel-Action dial, or
- STOP, your workout has ended – congratulate yourself.
