I've been working out using my father's membership at the gym. I've been working out for a little over an hour each day and what I do is stretch first, forward lunges, push ups, crunches, then I use the rowing machine and row for 4000 meters. After this I run a half mile and do my conditioning drills after wards to cool down. I was wondering if this was sufficient or if there is more i should be doing. I'm leaving for BCT in February after my nineteenth birthday. Any suggestions?
