Exactly. That's what I mean with Phase 1 and 2. Chris' boulder is one thing, but I can't take Jake seriously if he straight up beat up Ustanak with no enhancements.
I think the boulder thing is a common misconception, too. While Chris did pound on the boulder, it honestly looked like he was loosening it up where the boulder stood.
If you notice where the boulder is located, it's on top of an incline resting. Punching the boulder must've started it to move some after Chris was attempting to get it to roll with a "lift" pose. While punching it he was pressing his entire body weight against it, too. So at some point after wiggling it a bit forward with his thrashing, gravity took over and the inclined slope helped it move down.
