I started running with my dad when I was about 7. We ran 5k's, 10k's, 20k's and my pinnacle the Columbus, OH marathon. After that I quit running for years. But I've never gotten over the running buzz.

I've started running a few times since then, even got some new shoes a few years ago, but knee problems have grounded me (read: too much too soon). So I'd quit and restart months later.

You'll be hard pressed to find a cheaper yet more effective series of workouts for generating fitness than simple Calisthenics.

The Hindu Squat is a simple exercise.

• Stand with feet straight and slightly apart
