The GYM - Why does cost motivate?

So in my latest gym kick, I joined a new gym. This gym is not an ordianary gym, it is a personal training gym where they like to take things to the extreme. For some reason, just working out at 24 is not enough. The mere 20$ a month is costs me to have my membership is just not motivating enough to get me there.

HOWEVER.. the rediculous price of the X-Gym somehow motivates me to go to the gym. Is it merely because I know if I miss one session it costs me around $40 or if it is because I like to get my ass kicked every time I go. Needless to say, I go, and that is truly what matters. I wonder how long I will need this motivation to go to the gym.. because this is rediculously expensive, but, I suppose my health is worth the cost. :)

I am currently going to both gyms, X-Gym and 24 hour fitness so now my $20 a month is getting used also! WHOO HOO!

So apparently it takes at least $40 -- 2 times a week to get me to the gym. Maybe I need a better hobby :)
