Circuit training is a great way to achieve the benefits of strength training and cardiovascular training in one quick, challenging routine. The idea is to move
quickly from exercise to exercise, taking only as much rest between sets as it takes to set up the next exercise (less than 20 seconds). One circuit equals
one set of each exercise. Initially, start with completing one round of Circuit 1. Then add an additional round of the same circuit. Once you reach three
rounds of Circuit 1, add one round of Circuit 2. Add additional rounds of Circuit 2 as your fitness level increases. Repeat process with Circuit 3. Do not
let your heart rate exceed 220 minus your age. Perform each rep of each exercise slowly and with perfect technique. Count three seconds up and three
seconds down. Warm-up with 5-15 minutes of rowing or some other aerobic exercise before starting your circuits.
