Not everyone has time to get to the gym. If you're one of those people or even if you do have time for the gym, try out this quick circuit that can be done anywhere, anytime. No equipment necessary, since all you need is your body weight.
- Jumping jacks — one minute.
- Push-ups — one minute.
- Crunches — one minute.
Now alternate the circuit for 15 minutes or about five times.
