Using the ergo handle accessories will place your arms and hands in a more natural position as you exercise your arms and upper body.
Physical therapists frequently recommend the ergo handles for patients who are using the Magnetic Pedaller to exercise their harms, chest, back, and shoulders.
Recommended: When switching back and forth from the ergo handles and the foot pedals, using quick-connects are highly recommended. This will allow for quick and easy flow when switching as well as ensure the threads on the crank arms do not get worn out. Without using the quick-connects you run the risk of wearing out the threads and having to replace the crank arms. Two a pair.
