Set a goal and work to it

The key to an athletic body is consistent training, so in order to maintain the training and stop yourself from getting out of the habit, it's a great idea to set a goal.

This could be as simple as timing one of your training runs once a week and working towards beating it each time, or you could enter a race. Work towards the local 10k, half marathon or swimathon.

Be realistic in your goal though, because if it is unattainable you will get demoralised. If you can get a friend to sign up to the same aim then even better, you can then support each other.
