What exercises are you doing that stress ligaments, tendons, and bone more than muscle? I can't imagine exercises that would do that. All these tissues (including muscle) are being stressed with exercise.
You already have some good answers about what would help with recovery and repair.
Yep, it seems that I have discovered the answer, but that was just being confirmed by trial as I wrote my initial post. The specific exercise I'm working on is deep dips. I was use to doing the 2/3rds dips that most people do and a few months ago I decided to go deep, within a half inch or so from the inside of both armpits touching the bar. This, obviously, makes the dip into a totally different animal, as it feels like it's tearing the inside of my chest apart, at least until that area adapts to the new stresses. I did this in my mid-40's and became pretty strong at heavily-weighted deep dips. But my first try this time around last year was a near disaster, as my inner chest would not adapt (partially an age thing no doubt). I became so sore after about 5-6 workouts that it felt like I had gotten minor tears, and recovery took a couple of weeks from the last of those workouts.
This time with the cissus and the natural GH supplements recovery is fast and I can do a hard workout and be completely recovered to do another two days later. On my attempt a few months ago, I took two full days off, yet got sorer each workout until I believe I nearly incurred a bad injury. I also massage the area to get extra blood flow to the site with this new effort.
After getting good at the heavily-weighted deep dips 16 years ago, as I remember, most of my areas of chest strength took a big jump for a few weeks.
