Do you want to constantly move throughout your whole work out? Imagine getting on the treadmill for a quarter-mile, rowing for 500 m, or doing 2 miles on an air dyne bicycle, and interchange that with an 8 to 12 circuit workout. Back-and-forth you go between cardiovascular and strength. This work out can be modified so that a new person can work at their own level and anyone who wants to get after that day can work as hard as they can. A fan favorite at Results Only Fitness.
