I'm a junior in high school and I'm 100% sure I want to join Army ROTC in college and hopefully get an ROTC scholarship too. I physically want to be prepared for it before I join, so what should I do? I'm pretty sure I am fine on the running part because I run cross country and track. However, I need to work on my strength. Should I lift weights or just focus on push ups, pull ups and sit ups because that's part of the pt test? Thanks.
