The sparring was definitely a treat as that's something we have hardly seen from mayweather. The conditioning is great but anyone can be conditioned.

Now dude is shadowboxing with lady dumbbells (the rubber five pounders) Oh ****, now the tens. Fifteens. He's going up in weight every thirty seconds.
