I have a passionate dislike of gyms and fitness centres in general. But put me on a field, a pool or a court and tell me to run around after a ball, a disc or a shuttle and I will keep going all day. Which tends to result in a mismatch between my aspiration to play and the actual fitness level I possess.
As often as possible I try to simply incorporate a better lifestyle; so I walk or cycle to work (not across the ocean, obviously, that would just be silly) whatever the weather and use the stairs instead of an elevator for anything up to 5 storeys etc etc. But there is also nothing like a little incentive to make you more enthusiastic about actually doing something about it, and the Fitness Challenge is really good for that.
The premise is simple: In each 24 hour period starting at midnight you have to do 100 situps and 20 pressups (pushups). You get 1 day off a week and just keep going as long as possible. It is great and I have attempted to convince many people to get involved. Sure, normally I have had more than a couple of beers when I try to convince them so I may not be the most persuasive advocate at the time; hence this approach.
Oh, and the final cool thing about it: You are doing a ‘worthy’ thing and most of the $15 it costs to join goes to charity. Well there is nothing like a little cash involvement to keep you committed. Anway, sign up for it by sending an e-mail to firstname.lastname@example.org and tell Fred that you know me.
