The Circuit7® routine incorporates the proven results of circuit training, and takes it to another level. Because you hold the next exercise in your hands, it allows for rapid movement from exercise to exercise. This means you do not waste time moving from machine to machine, waiting in line, or reconfiguring your all-in-one home machine. And because it is completely portable you do not waste time driving to the gym. You can workout at home, at work, on the road, or even at the beach on a sunny day.
