The step-up is the quintessential functional exercise requiring balance,
coordination and strength. Adding a medicine ball twist to the step-up is a
great way to challenge your balance as well as work your obliques and even
shoulders. The medicine stepup twist is an exercise which is best used as part
of a dynamic warm-up. In addition to using the medicine stepup twist as a
warm-up it can be used as a bridge between resistance training exercises of
un-related muscles in a circuit training workout program.
