Hammer Strength inclines and dumbbells.
The only other movement I used to do was the smith machine press on an incline...but I don't like the feel of it anymore.
That's it. Nothing magical. Just lots of heavy weight, food and time with a huge focus on getting stronger.
I see so few on this site even coming close to a 405 bench lately. It is like some believe it is impossible.
No one builds a massive chest with baby weights.
