Pre-BCT Workout Priorities (in order):
1) Just workout -- kind doesn't matter as much as just getting
your heartrate up and muscles working at least 5x per week
2) Work on your weaknesses -- If you are a slow runner, work on
cardio. If you can do squats forever but have a weak upper body,
work on that. If you are not a runner, use this time to build up your
leg endurance. As mentioned, you do not want to develop shin splints
in BCT.
3) Focus on body weight exercises -- common bct exercises
include various forms of pushups, flutterkicks, squats, pullups, jumping
jacks, body-builders, front-leaning rest, wall sits, sprints, etc. The
static stuff like front-leaning rest (for 5+ minutes at a time) can kill
you if you haven't practiced. Remember you will be working out while
wearing about 15 extra lbs. of uniform and water.
That said:
a) Preparation is very important. Some sweat now will save you from a
lot of extra attention later. However, don't let working out rule your
life. You have 3 months left with your family and friends. Don't waste
that time.
b) Don't get hurt. If you've only ever run 2 miles at a time, don't go out
on a Saturday and do 15. Slow, steady, injury free progress is the
goal. Additionally, don't go out with friends and do something stupid.
I'm not saying don't have fun with your last few months. I am saying
wear a helmet and be conservative. I'm a snowboarder and skydiver,
and understand that most activities are safe enough if you are
careful. If the little voice in the back of your head says that
jumping off the deck into the pool on a Friday night isn't really a good
idea, listen to it.
