Here are some program design thoughts to consider as you get older:
- you need mobility via massage too remove adhesions and restore length.
-you need a lot of extension work for anti-gravity muscles.
-you need tons of glute work and lower body work (preferably unilaterally).
-you need shoulder stability work after the extension work.
- use heart rate recovery, approx. 20-40 beats down from your highest during the interval to let you know when to do your next set, if you're performing interval training, rather than using the work/rest ratio 1:3 , 1:2, 1:1, method.
