Use the beginning of class to warm up your deadlift and get to the weight for the metcon. It should be heavy – if you can Rx the weight, then do it, but if not then use around 75%.
Although it says 10 rounds for time, this isn’t necessarily going to be a sprint. You may do singles for the deadlifts and need to setup and brace yourself – that’s fine.

10 rounds for time:
3 deadlifts, 315/215#
6 HSPUs
9 wall balls, 20/14#
