Some comments while previewing:
If you got tired of watching Cathe and crew high five each other during the breaks, you won't like this.
They are doing it less as the workout goes on.
This is very high impact. I'm used to high impact but they look like they're literally stomping the floor with this impact, so I hope they have an excellent floor. There is a modifier.
They are repeating drills. It looks like each drill is done three times.
The little timer clocks are small. Too small for me to read.
Chalene previews the moves during the rests.
