Delt work doesn’t have to be heavy. Doing lateral raises with the proper form is actually pretty light work. Here’s the video that was posted in a thread about isolating the delts. It’s actually pretty good.
With this setup you could do the bench and OHP on day 2. If this were a MWF split then I didn’t like it since you were doing so much pressing on Day 1 and then hitting your 5/3/1 OHP stuff on Day 3.
