I had been getting various aches and pains related to tendons / ligaments now for the last couple of years.  I was hoping my low estrogen / testosterone was the main cause, but I am getting older so who knows?

In the past I pretty much never got that sort of problem.

I am not even sure I would elevate my knee pain to an actual injury, some sort of patellofemoral pain syndrome, IT band tightness, combination of the two, hard for me to tell.  The only thing I know for sure was that I caused it by excessive stair climbing.

I am pretty sure the IT band was getting way too tight, I could feel a little pain if I kick back one leg while standing.  Massage on that part of my leg hurt.

I tried form rollers and various stretches, it helped a little, but the cable exercise seemed to somehow counteract the problem.

I had been getting some plantar fasciitis in my left foot when running / walking, I used some old bicycle inner tubes to build up a custom orthotic by cutting them into small pieces and gluing them into a small pyramid. That seems to solve that problem.

Then my bike seat was a little high, which I believe caused pain like a groin pull, which I went to therapy for.  That went away after a while, I still do the stretches they recommended during therapy.

I got some sort of tennis elbow type problem from using the elliptical machine at the gym, I believe i was pushing too hard on the bars when using the machine, if I go back I try and have a gentle hold on the moving arm, or use a machine with a fixed arm so I am not tempted to use my arm to aid my legs.

I still use free weights, but mostly for bench press, some curls. I used to do squats, but the bar tends to hurt my upper back.   I might get a Manta Ray Type - Barbell Squat Pad, I think that would help a lot if  I want to do squats.

But I read about people that have much more serious problems, so I am grateful that my problems are minor in comparison.
