You should keep improving your form & mobility to make better use of barbells, dumbells, and machines, but if you really struggle with chest activation, give these 3 a go.
3. Wide Pushups
The fact that your hands are so wide allows your chest to stretch further than it otherwise could by the time your torso hits the floor. Same principal applies here as on the bench, narrower grip = more triceps & less chest.
The main thing I learned from this experience:
If you want to get yourself to do things under-stimulating (reading, going on walks, writing), you have to make yourself bored enough that these things now seem stimulating again.
This wasn’t an endorsement for diet cults or excessive ignorance as it relates to your training, just a reminder of how simple the game can be when you cut out the destructive habits & don’t overcomplicate things.
I now eat like less of a sociopath & enjoy the occasional night out but I’ve stayed consistent with the fundamentals & the results have stayed largely the same.
