I'll start by saying i am about 4 stone overweight and have been for about 7 or 8 years. I've exercised a fair bit in the past with no issues but in the last year or so I injure myself whenever I exercise. I'm not talking aching a bit the next day. I do follow instructors in classes etc to make sure I'm doing moves correctly but it still happens. In Jan I did yoga and after 4 sessions ended up with a pain in my right hip that is still there. I did parkrun on Saturday and ended up hobbling for days with pain in my foot and calf. Anytime I do weights even small I hurt by neck and shoulder. It's driving me mad and putting me off exercise. What could the issue be?
