I was crushed up in a car accident a number of years ago (23 breaks in the pelvis, broke both legs, crushed arm----head on with a school bus). For years I could barely get through physical therapy, never mind exercise. However, I have found that deep water aerobics (and please everyone, spare me the I won't be seen in a bathing suit crap -- when I started I weighed 320 pounds) has immensely helped my balance, endurance, flexibility, you name it! I also do a bit of water pilates, and now have strengthened to the point that I am able to do some light weight training and circuit training. I now am at our local Y 5-6 days a week, it is as much a part of my day as breathing. Oh, yeah, I am now down 80 pounds (and still working on it)-----I will be honest to say that getting on bioidentical hormones helped me tremendously to give me the focus and energy to start working out, but I honestly know that my working out has kept me off the crutches and cane. Best of luck to you!
