Pre Max question

I’m assuming you’ve been working out regularly, and understand how to stretch and warm up properly, so this would be my approach:

First off, for at least 4 weeks leading up to it, you should be doing one light warm up set of 8-12 reps, and then jumping into heavier sets where 3-5 reps is your physical limit, but no more than 6 sets each workout. Gauge your strength by taking whatever your 3 rep max is, which by my best guess would be around 210-215 before being able to achieve 225 comfortably.

On max day you want to be at full strength, but not fatigued.

Here’s what I’d do specifically on that day:

Cardio to get the blood pumping followed by stretching as well as some exercises to prime the chest and back, which for me would be pull ups, lat pull downs, single dumbbell skull crushers, dips and push ups.

After you’ve warmed up and are ready to hit the bench:

1 warm up set of 7 (70%)
1 working set of 3 (90%)
Go for 225

I would give it 3 attempts with plenty of rest in between any failed max rep. If you can’t hit the mark, then take at least two weeks in between your next max day, then repeat.
