@katy89 If your weight is going up and you're plateaued on BB Bench for 2 months, it could be your triceps. A lot of people don't take overhead tricep extensions, tricep pushdowns, skullcrushers, JM Press, etc. seriously and train those at 7 RPE at the end of push/upper body/full body day because no one gives a fuck about those numbers. Tricep extensions are easy to cheat too. Which kills gains.
Also for 85kg bench, I think it's easier to go up 2.5kg (if you have micro-plates, you can go up less than that) than it is to get grind 1 more rep. Use a 1RM calculator to check. This is especially true for deadlift, squat and Leg Press. Basically any movement with lots of load.
Also I do feel that 30D DB Incline Press is better for chest than BB Bench. Jeff Nippard mentioned that in the literature, 30D DB Incline Press does still have significant mid/lower pec activation. I haven't done DB Flat Bench in like 3 months or BB Bench in 8 months and my mid/lower pecs aren't lagging. DB Flat Bench is perfectly fine to do as well. As is Smith Bench.
