Currently I'm training via crossfit and also strength training and doing cardio at the gym. I'm building a good foundation, to being able to follow Get Selected / NSCA Tactical Athlete Program workout routines without injury.
Cardio: Currently I'm interval training with sprints at goal pace and retesting mile and 2 mile runs, to track progress weekly.
Strength Training: Im focused on muscular endurance (i.e high reps low rest) as I currently have a good platform of strength to do majority of things outlined in books I've read, but absolutely nowhere near the muscular endurance to do so.
Mental: Reading a ton, Ive got Get Selected, Chosen Soldier, In the Company of Heroes, Little Black Book Of Violence, U.S. Army Map Reading & Land Nav and will soon be tackling some of the suggested reading in Get Selected.
One a side note: One utility I've found to be helpful is the NSCA's Tactical Athlete training program. Use your google force to find it, otherwise I can assist you in obtaining a copy. I would value a BTDT program over this one any day but it does have pretty pictures for my simplistic 18X brethren j/j. On serious note I was a member of the NSCA and can attest to the big brains over there when it comes to the human body and structuring strength training programs for specific athletic endeavours and the pictures and write ups of the exercises therein are extremely helpful.
Ill be starting the NSCA program next week and if you care to PM and ill let you know how its going and be able to give mroe details about it.
