That's not that hardcore. The trick with chopping through a bunch of boards or cinder block is the spacing in between each piece. Rather than chopping through three inches of cinder block, he's chopping through one inch of cinder block three times. When they're spaced there's not much loss of momentum when you strike through and almost anyone can break a decent amount. Cinder blocks are brittle as hell. I'm pretty fucking scrawny but if I didn't care about breaking my fist I could probably do that.
