@peemee Strengthening exercises are a very very good idea. When weakness sets in, it can start a downward spiral: not doing much, so getting weak, so getting injuries and pains, so not doing much, so getting even weaker. Don’t take that the wrong way. I’m not saying your problems are self-inflicted because of lifestyle. I know you have circumstantial problems and ailments you can’t cure. I’m just making a general point for all of us about not letting ourselves get weak.
