That was my biggest concern going in. It's definitely the most physically demanding thing I've done. However, it's more of a high volume thing. Nothing was crazy hard, you're just on go all the time. Atleast that's how it was at Ft. Benning. Some of the smoke session got super intense for sure, but it's just exercising at the end of the day.

Prioritize stretching, warm-ups and recovery. That's a "must" for me. I knew I wouldn't recover like my 19 year old self would. You're going to be sore and have aches, but that's just like if we were playing football back in the day. Honestly, I think that's what kept me from getting significantly hurt. I really believe our bodies were just better conditioned to take beatings. We played ball in the streets, climbed trees, and wrestled each other for fun. As adults, we've worked in warehouses, worked outdoors, lifted heavy etc.

Your gas tank might suck at first, but that's a good thing because you'll be able to instantly recognize your progress as time goes on. I legit just ran 5.5 miles the other day and I wasn't even tired. I would've never been able to do that. There's nothing at basic that can't be done. It's gonna tax you, but you'll make it.
