. When you see 5+, 3+, or 1+, that means you do the max reps you can manage with that weight, with the goal of setting a rep record in each workout.
That looked easy. However, 100kg isn't 225lbs, it's actually ~220lbs.
Also, can't really tell from the video, but it looked like the bar didn't touch your chest? And on the 3rd rep, your butt seemed to have come off the bench.
I'd use more of an arch, and take a bit more time setting up for the lift (shoulders pulled back and down, getting that tight arch, anchoring your feet onto the ground, etc), but otherwise, you looked like you have a few kilos more in the tank.
Have been keeping a close eye on this log as I started smolov jr bench too. And awesome job on the 2pps man.
You just have to be very specific to your spotter about what you expect. Something like "Do not under any circumstance touch the bar until I shake my head/nod my head/say my safety word/etc".
