i much prefer p90x because its more "manly" workouts. I hate cardio, so if i can be tricked into doing it through lifting that's a good thing for me.

all you need is a pullup bar and some resistance bands
you can run whatever optic you want. Its your gun! I have a red dot on one rifle, and ive attempted shooting yotes with it haha it was fun but definitely not ideal... atleast for me
it's cool lookin, don't get me wrong. it does sorta look like a sign for a sushi restaurant tho.
