I am one of those people that doesn't have a reason to go to the gym so I never promise myself to go. And since I look at my money situation before spending it, I know it is too expensive due to the risk of ending up not going but still paying. People with money to spend easily spend it on things they don't need. Too bad not everyone is really conscious about their ways so they think they can promise themselves something but in reality there is a super high probability they won't keep the promise to themselves. You can tell people a hundred times they won't keep their promise and the reason and whatever, they will still think they can keep it because their motivation is still high because they haven't done anything yet. Gyms here have trials.
