Thanks for the input everyone! I completely forgot I posted this until I stumbled upon it again this afternoon.
I started exercising almost 2 weeks ago. Right now I'm just doing some non-weight bearing leg exercises (from physical therapy) to strengthen the muscles to support my knees, some core/ab work on the balance ball, and I've done 2 sessions of arm workouts - I googled PT exercises for shoulder pain. My shoulder is very unhappy with me since the second workout - so I'm resting that now.
Starting in June I will be babysitting my best friend's little girl 3 days a week. She has a pool so I'm going to incorporate some aqua cardio then.
I'm hoping that by the time August rolls around and I'm back to school, I will have lost enough weight and build enough strength to go back to the gym.
Every day is a battle, but whatever, I'm scrappy ~Darcey
