Cross-train most days of the week on several different cardio machines. Each session here burns 300-500 calories, depending on your fitness level and body weight. Cardio equipment and light weights for the circuit cardio workouts are required. Be sure to cooldown and stretch thoroughly after each session! Move at your own pace and drink lots of water before, during, and after these fast-paced routines.

This six-week program includes:

Cardio Treadmill Hill: Chris Bohlin
The safest, most portable, and do-able cardiovascular workout is a power walk. We start you off slowly, so you nail proper walking form and pacing. If you want a more intense or longer walk, keep putting one foot in front of the other!

Fullbody Gym: Chris Bohlin
This fast-paced resistance workout uses strength machines like leg presses and tricep pull-downs to target your whole body. You should have intermediate knowledge of gym machines and strength workouts. You may need to warm up and cool down thoroughly on your own, and you do need to know your way around the weight room.
