1st workout at new gym!

This was my first metcon in a while, and it really kicked my butt!
First, I did true crossfit warmup (I was unaware that we hadn't been doing that thus far)
So ten total minutes on rowing, 4 min regular warmup, then did 20 second bursts at 2:20, then 2:00 pace, then back to regular speed.

Workout: 20/10/20/10
3 Rounds for time:
* 20 wall balls (8lb ball, 8ft)
* 10 pull ups
* 20 20lb kettle ball swings
* 10 cal row
--> 1st round, 4:10, second round 4:30, 3rd round 6:47 (YUCK!) the wall balls really slowed me down-I have got some work to do to play catch up!
