Progression strength speed with lifts

Deads were the fastest for me.

Squats, over time, have probably been second fastest. Bench, I plateaued for a long time until I fixed my form.

You just have more capacity to add with dead and squat. Beginning to current, I've probably added close to 400.

I’d say squats for me. I got thick arse legs. Followed by deads. Bench and OHP are hard gainers, but I’m not too bad.

Right. You have some big, powerful muscles controlling squat and dead. Absent something weird, they should always outpace bench.

Your chest and triceps will never match glutes, hams and quads for pure power output.
