why do we work out?

So recently i joined 24-hour fitness membership (because i joined the hip hop dance group) and that's where we practice... i was browsing through 24-hour's website and found a picture that pretty much culminates why we work out.... is it to live longer? is it to fit in those pants that we bought 5 years ago? is it for that highschool reunion that's in 4 years?

no... its quite simply the two reasons shown on the tshirts below...



i want to get that dood's shirt and wear it while i'm working out at the gym... bahahaha... and yes... that's my reason...
