Great question and one I am currenlty facing. Have you tried just walking in a pool? That is my goal as soon as it gets warm enough for me to go out to the pool. i have done that before with great success. Otherwise, I have found that I do what I can when I can. The weight comes off slowly, but that's better than quickly.
Good question I asked it too. Didn't get a satisfactory answer. Maybe a personal trainer if you can afford it. I don't know much about them except I have a nephew who is one & I know he had to study all that stuff in school. Maybe one could help you at least develop a plan. Just a suggestion
Check with your local YMCA- exercise in a heated pool is the best answer!!
My Doctor said eat less.... Very helpful.....Not!!!
I lost 35 pounds on Weight Watchers and didn't exercise.
