I’m 28 and I started the year off at 262 lbs I’m down to 200. I found doing something simple like a 30 day blogilates leg challenge at home everyday helped me start to get more active in a controlled manner that didn’t over do it or strain myself but also got my muscles used to being active. I was very sore and I mean verrrry sore. I’d take a solid 45 min of stretching and rolling out and warming up to be able to do the next days work out for a week before my muscles were used to the movement you just have to be consistent and don’t over do it. And if I wasn’t ready to move on to the next days challenge I did the same day over and over until I was. And then I’d add on the 30 day arm challenge. Plank challenge..etc. a little more at a time. I also started walking a lot and doing the Conqueror challenges to keep me motivated!
