Great job taking that step. The hard part is staying motivated an going on a consistent basis. What is your goal? Lose weight or bulk up?
No, the hard part is to actually work out in the middle of perfect strangers.
I actually escaped that by buying the most needed stuff and actually work out at home. You honestly don't need that much stuff.

Also I just want to add that exercise shouldn't be the only thing in your life. I ended up spending a lot of time and energy on exercise so when I missed an opportunity to get ahead in life (mainly because people were ignoring me as if I was some sort of meathead) and found myself waiting for hours to see a sports medicine doctor after getting a sports injury that completely undid all my gains, well, I felt preeeetty stupid!
