Jim, due to a combination of work/family time constraints and a pretty-lengthy injury history (past surgeries on low back, ankles and rotator cuff), I found myself drawn to a "low volume" style of programming. Right now, I am trying to set up a 2-day week routine that would take about 45-60 minutes per workout. On other days, I try to fit in mobility and light core work when I have a few free minutes and also try to walk daily. Any thoughts are greatly appreciated. Love your style of programming! Thanks.
