Do you want to look strong/powerful or be strong/powerful? Or is it strength and athleticism?
I’m having trouble figuring out what exactly your current goal is?
For athleticism I like:
Olympic lifts
Plyometrics - Lot of jumping variations
Strongman training (Tires/sleds/sledge hammer/etc…)

For strength :
5/3/1 - simple & effective way to increase numbers in the big 3.
For the power/strong look :
Defranco
-Built like a badass
-West Side for Skinny Bastards
