Day 9 - Plyometrics

Plyometrics again already? Wow. Today's plyo was really good. I'm getting a little mad about the fact that the puzzle mats I'm using won't stay together and the whole assemblage always rotates to the right and back while I'm exercising. I have to move the mat back to position after almost every set. It's still better than nothing, but I need to look at other options. Or glue and carpet tape. Not sure if that would help.
