Cograts on losing the weight! That alone will help you to tackle such a great physical training program as pilates.
I trained and worked at a gym for about 5 years, (BC- before children.)
As someone, (ahem) over 45, I can tell you that pilates along with a healthy diet and some cardio time is probably the best way to stay in shape for those over 40 or anyone just starting out with an excersize program. Swimming and water aerobic classes are also great low impact workouts and therapy especially for the lower extremities. All least these routines work for me.
I highly suggest you take a few beginner pilates classes with your doctor's recommendations for all of this, of course. You will be surprised how quickly your core muscles will respond to this type of controlled training.
When you are comfortable with the beginners stage, slowly advance. But relax and take it easy and above else be consistant and...have fun!
