The reason I asked was I think that you may be questioning yourself how much is too much. With cycling, walking , running, swimming ? and the gym quite obviously your exercise regime is far beyond what is required for good health. I have done a lot of gym work over the years and have always seen it as a means to an end not an end in itself. Why ride an exercise bike indoors in a germ laden environment when you can be out in the fresh air, or row a none existent boat up a none existing river. Lifting weights is pointless unless you want to develop strength for a specific purpose but what you develop will disappear anyway when you stop as the body only maintains what it needs, not the artificial loads imposed by weights. If you have joint problems putting more loads through them with weights is probably counter productive.I think you mentioned developing a six pack somewhere, concentrating on one abdominal muscle group may in fact have a destabilising effect on your pelvic girdle exacerbating your hip imbalance. For your joints, running and cycling it may be worth getting a copy of Joanne Elphinson's book Stability, Sport and Performance Movement. as it will probably do more for your hips, shoulder, running and cycling than any amount of gym work.
Your wrist problem on the bike is almost certainly a positional issue putting too much weight on your hands, you could try moving your saddle back a bit see if it makes any difference.
I hope you don't think I have been too blunt, it is well meaning advice from someone who has been there.
