Patrick Vellner blew us all away with his performance during the Open — particularly with his heavy clean during the 18.2 live announcement. Now we know how he’s gotten so good at Olympic weightlifting: really challenging complexes. Here’s one he tackled for the clean and jerk.

Here’s one more he did with the snatch. We had started to count how many reps it was, but gave up in the middle. Watch and you’ll see why.

Complexes are helpful for learning how to maintain speed and technique when you’re feeling fatigued. Will you try these at the gym?
