Overall toning workout

This all-round routine is called the triple 20: 20 minutes of cardio and 20 minutes of circuit training, finishing with 20 minutes of stretching. The final segment is especially beneficial for people who sit at a desk all day. Repeat each circuit training exercise ten times. After completing them all, rest for 60 seconds, then complete at least two more sets or as many as you can complete in 20 minutes. Always remember to breathe. Hold each stretch for 15 to 30 seconds and perform each stretch twice. Concentrate on breathing for the entire duration of the stretch.

(3) Finish with a five-minute cooldown walk at 3mph.
