JMM makes me nervous everytime he does this sht...

**** yeah!!! Viva el pequeno gigante de Neza

Im sure he knows what he's doing. He's probably hit the speed bag tens of thousands of times or maybe hundreds.

Mayweather couldn't pop a speedbag tho

Floyd still outclassed Marquez doe.

It's kind of silly honestly. It's easy enough to pop a bag from normal hits. You really don't have to try very hard. I feel bad for the guy changing the bladders in those constantly. That **** is no fun!

muscle memory. I think his body knows how high to punch and he's probably done it a million times.

Floyd still outclassed Marquez doe.

Virtually impossible he was juiced up with USADA testing.
