Interesting on your isometrics routines. I believe Jack LaLanne used them at times. Since I've gotten older, I've utilized some of his ideas on using lighter weights and higher reps. The thing I've noticed about age, it affect joints and ligaments first before the muscles.Is going to be very minimalist. Only a doorframe, basement jack, small tree etc will be needed.
Have been working on the specific exercises and they will undoubtedly evolve somewhat over time, but basic stuff.
The holds themselves will be about 4seconds on followed by a quick 2-3 second unfolding/extension/flexion of the target joints, this sequence repeated 10x equals one set.
I'm not sure what to expect for adaptive response. Am hoping to get good holding and grind strength plus a bit of hypertrophy from the added muscle lengthening/shortening between exertions. The tinkering I did leading up to this has been pretty promising.
Starts up tomorrow and I'll post up some videos in a week or two.
