Circuit training is a fabulous, quick way to build an effective workout. Move through several exercises in a row to keep your heart rate up and your body working, but without exhausting one muscle group. You’re rotating through muscle groups and targeting different areas, so while your triceps are working, your abs, chest and back are mainly resting; while your abs are feeling the burn, your triceps, back and chest chill out.

This routine requires no extra equipment—besides a chair, bed or bench—so there are no excuses to skip it! (This also makes this program ideal for a hotel or dorm room). Feel free to include some jumping jacks, jogging in place or jumping rope in between each routine: try the four strength exercises, do one to two minutes of cardio, repeat the strength moves again, pick a different cardio for one to two minutes and finish off with one more strength rotation.

So throw on your workout shoes and join me!
