Define your body with this highly effective, super intense workout! Using dumbbells and a step you will do mini-circuits that work on strength, endurance, core control and power. Each mini-circuit involves a lower body exercise, an upper body exercise and a power/plyometric drill. Repeat the whole circuit for two sets to build intensity and enhance the training effect, or if you’re just starting out or are short on time, do just one set. The workout finishes with functional core work and a relaxing cool down stretch. This video demonstrates a progressive circuit training program design that trains multiple fitness components in a single session.
