Okay, been getting a lot of work in with the small chest plate. Hope this helps.
Get on your traps, then give little rolls side to side until you get your scaps pinched as best You could. By that time you will have lost your traps a little. Wrists on the inside of the knurling, pick yourself up a little and have your handoff guy get you back on your traps. Then do whatever it takes to get your hands out. I have yet to need assistance getting my hands out, but we've all seen it. Your legs and lats will also be important to keeping on your traps and keeping chest/belly up.
Next part should be more effective yet. Receive the handoff totally 100% locked out. The bone on bone is important so that the weight transfers without effort all the way down into the pad. Keep your lats tight and pulling the bar out, but relax your scapular retractors and let the weight push them down and together. When it's fully settled, the chest plate is now loaded all the way to lockout. Lock that down, keep it, bench big.
You had a nice first day back. 90% for seven reps is good stuff.
