Sumo deadlift high pulls is a classic crossfit move. Sounds like you had a good workout. We did so many squats this morning that I am going to be pretty sore.
High pulls, not hyper! That's it. They're a bit crazy - he held us in the start position for ages and that was way more difficult than the move itself.
We're not quite into good workout territory yet, but we'll have finished the on ramp by next weekend, and then we can start with the big ones!
