Do fighters train at all during fight week?

Light training yes, but nothing that's going to risk injury.

 

I know Floyd spars 30 rounds and runs at least 100 miles during fight week. After the weigh in, he spars 12 rounds and runs some more and sometimes becomes severely dehydrated and needs an IV.

 

If they need to cut to make weight then of course. For guys like AJ and Povetkin I doubt it. Light workouts and pad work to keep sharp probably.

 

Mostly at the beginning of fight week but not much the last 2-3 days.
