For all the young folks out there who are trying to get ready for CFAs and Beast, I would encourage you to consider Crossfit. We have found that it's the best method to keep our guys in top shape without spending whole days in the gym. Essentially, the website publishes a Workout-of-the-Day (WOD) and that's the plan you follow. Alternatively, you can seek out a local Crossfit gym, which will have trainers to guide you through the workouts. If you can smoke Crossfit WODs by the time you report, PT won't be a worry. Even 8 solid weeks on Crossfit before you go to BCT will provide you with great core strength, which will help you with everything from PT to rucking. Go to www.crossfit.com to learn more. (Crossfit is free, btw, so I'm not plugging anything for personal gain). Best of luck!
