Rode my exercise bike for 18 1/2 minutes yesterday. I was going for 20 but my knee started to hurt so I stopped. I figured if I kept going I would hurt today and not get back on the stupid thing. I really hate to exercise. I find no joy in it at all. I know I should be doing it everyday and trying to go longer and longer. I really can't stand it. I imagine one big reason is all the pain I am in. But I need to keep going so I can get this weight off which is the cause of most of the pain.
