Just joined today. Am a 56 year old, about 5 stone overweight and apart from some minor back issues and a touch of arthritis am fairly fit. Recently had issues with very, very swollen feet and ankles but it seems that was due to the heat. Just been told my cholesterol is a little high and that i should try to reduce it. Advice from GP is to change diet to a cholesterol lowering one and to exercise. I already do at least 2 sessions a week at a local leisure centre. This week i have done 1 hour in the gym, swum over 700 meters (a few weeks ago i struggled to swim 100) and just done a pilates based exercise class specifically for back problems.
