Where does your first growth spurt occur?
During your very first workout at the gym
As you walked through the gym's sliding glass doors, you took a deep breath. This was your first time setting foot inside and this would be your first time actually attempting to workout since PE classes in school almost a decade ago. Trying out a gym and exercising has been something you've wanted to try for a long while and kept putting off. It's not like you were in poor shape of course, you considered yourself in fairly average shape overall really and weren't too unhappy about how you looked. There was always room for improvement though. You had been on the weak and scrawny end of things for your entire life, with Nick occasionally joking that you could get overpowered by a first grader. It wasn't far from the truth though, and now that your soon to be husband had bought you a membership it was time to dive in and give it a try.
You were sporting a very loose fitting tank top and a pair of equally relaxed shorts, your outfit carefully chosen to not show off much of yourself. The idea of anyone watching you working out was embarrassing enough, you certainly didn't need to give any reason for people to pay more attention to you than you wanted.
After swiping the membership card at the front desk you walked in, gawking at the wide array of machines and weights and the seemingly endless array of options. All of the choices left you staring off, slightly overwhelmed and trying to decide what to work on first. Thankfully the place didn't look too busy, there were just a few handfuls of men and women exercising which left a plethora of spots and machines open for you to choose from. Hit the weights to try and get stronger and build some muscle? Maybe some squats for the rear end? Starting with leg exercises to see about making you bigger and better there?
