Hello,
I had an operation on my ankle is September. I'm still in an air walker boot and have found out the op went wrong so I'm due another one in the next few months.
Problem is, I am desperate to lose this weight. I've never been one that had to watch my weight as I was always so active so I'm learning with food. Trouble is, I have almost 3 stone I'd like to lose and I'm worried il get all wobbly and loose!
Are there any tips and exercises I can try to keep my body tight or am I fighting a losing battle until I'm healed? My biggest problem area would be my thighs for wobbling lol!
Any help really appreciated. Thankyou x
