As for PT, I've been sticking to my regular routine of 6 days per week Monday-Saturday. I have been substituting a lot of free weight sets for bodyweight exercises. This increases my muscle endurance and removes unnecessary muscle mass. I also focus a lot on stretching before and after my workouts.
I am at the gym Monday-Friday. I split my muscle groups each day, and I end every PT session with a run or other types of cardio (30-45 mins of working sets/ 30-45 mins of cardio). Monday is chest/biceps/core/run; Tues is legs/core/aerobic cardio; Wed is back/run; Thurs is shoulders/triceps/core/aerobic cardio; Fri is my anarobic full body day, I switch between P90x/Sparticus 2.0/The 300 workout/etc.. (whatever PT that I am unable to catch my breath during the course); Sat I do my long run.
I use the runnersworld.com Smartcoach program for my running schedule, available on the PC and smartphones. I recently set it up for a 5k race taking place on April 15th, but you can set it for anything from 1 mile to 26.2 miles on any day you want. The free program works pretty well to gradually increase pace and distance which prevents injury while strengthening muscles and tendons. I used the free program for marathon training.
I am not a personal trainer by any means but if you have any questions pm me or talk to me on Facebook, as I am also a member of the OCS FB group.
