Both my back and my forearm are feeling much better. I can make my arm hurt if I stretch it out and then twist, but only marginally. I'm thinking give it another week and then have a deadlift day of up to 405 lbs to see how that feels.

Yesterday I Yukon squatted up to 420x5, essentially making good on my last attempt where I got 3 and had to rerack because of my back. Did drop-down sets after of 365x5, 315x8, and 225x8. 

Came back today and did some band-resistant good mornings and 5 slow reps on the ab wheel, pausing mid-way to do a nasty plank variant.
