Let Go

Far too many exercisers hold on to the cardio equipment their using. Holding onto the machine is certainly good to do when changing speed or resistance, but let go whenever possible. By holding onto the supports, you minimize the efficacy of your workout by reducing how many muscles can be in action. You're essentially resting part of your body (at least a little bit) by holding on.

This is especially true on stair climbers or treadmills at a high incline. If you slow down or decrease your incline, and don't hold on, you'll get a much better workout and get fitter faster!
