Hello,
Your doing great at 42 lbs great job! Didn't your doctor put you on an exercise program from your initial consult? I got an exercise program and diet consult, but my surgery date is 6 months away. Well, you can find workout plans if you google the areas you want to target. I just started an exercise program which I have not done any type of exercise in 10 years too! Start off slow with just 15 min 5 days a week and then increase up your time. I do 15 min of the treadmill and then 15 min of weights and then 15 min on the treadmill. Good luck and keep it up!
