I hope you find that sweet spot. Really took years for me to find "old, worn out guy" friendly exercise programs. They really aren't out there so you have to figure it out on your own. My combination of the HIIT machine and Pilates is pretty low impact on my rebuilt should, repaired back and "modified" ankle. So far so good :thumbsup: feel better, toning up a bit and energy levels are up.
I deal with leg cramps as well. Magnesium before bed helps me a lot. Sucks to get launched out of bed because your shin and calf muscles seem to want to fracture your tib/fib :eek:
