techniques for geezers
Take it from an older guy - don't do too much impact on a daily basis over a lifetime.
This geezer does mostly low impact aerobic conditioning (i.e. x/c ski machine with sprints every 2 minutes); that way the bod still works without problems for the less frequent b ball games.
The other thing I've done is lift lower weight, increasing the # of reps while lifting the weights up and down slowly. Keeps you from bulking up and makes you quick-strong for martial arts kinda stuff. Burns more calories. Learned this from female body shapers. It really works.
