I know this isn't a running forum but couldn't find the answer on Google and I'm not a member of a running forum so...
I'm from a Subtropical climate and now I live in a Tropical climate. 70degrees F is cool to me and any lower is chilly. Is there any way I can prepare my body for colder weather, specifically the running that I do but also the pull-ups and sit-ups.
Right now I live on a tropical island but I'd like to join the Marines and am worried that the cold will be a big problem for me. Any advice or tips would be great. I do my sit-ups (and basic strength exercises) inside but running, pull-ups, and some plyometric jumping outside.
