To call this program hard is an understatement. The volume is high, the work is heavy, and you'll want to quit. But I can promise you, your back will never be thicker and your PRs will become something of the past.
Don't let those creepy eight-legged critters stop you from getting a good workout. Instead, use them as inspiration as you do spider crawls and spider curls in this workout of the day. Or pretend to smash them. Yeah, that'll work.
