Earlier this week, Floyd Mayweather posted an Instagram video that showed him chopping wood with an ax. Many media outlets, including us, drew the parallel to the old-school training method of Rocky IV.

In two new videos posted to Facebook on Thursday, Mayweather confirmed that this was a back-to-the-basics approach as he trains to face Manny Pacquiao. He said he began chopping in 1987. (That's consistent with the timeline of "Rocky IV," which was released in 1985.)

As you can see, these are seriously large logs that Mayweather is chopping. Two of his security guards were in for a surprise when they had to set up the logs for Mayweather to chop. They thought they were coming over to his house just to hang out and didn't realize they would literally be asked to do some heavy lifting.
