Confident extroverts like fellow Leo Mick Jagger have no trouble sticking to a strict regime when it's set - anything that will appear to their dogmatic, impulsive and somewhat vain character traits.

While you will be adept at going it alone, your broad-minded strength (and temptation to interfere) will suit you well around others so why not join a gym or fitness team?

Clubs like Slim Fast will give you a regular weigh-in and allow you to compete with those in the group, but don't go too wild or you'll end up stick thin and unhealthy.
