I've changed over from Phase 1 heavy (for me) lifting to Phase 2 high reps on 2 lifting days and a fun day which is more like a CrossFit day, as my running miles increase getting ready for my 100m race in Feb. Purchased some knee braces from Mava and Shock doctor for exercise use and recovery. My knees are getting a little worn out from decades of boybuilding and a couple decades of ultra endurance training. Got a massage roller bar to work out some of the knots as miles build up.
