I stumbled onto this one mostly by accident. While democratically trying to figure out what to do, my workout partner and I came up with a nasty combo.
Start a running clock:
At 1 minute:
5 Rounds
5 Handstand Pushups
20 GHD Sit Ups
At 20 minutes:
10 down to 1
2-KB Snatch @ 16kg
OH Walking Lunge w/ KBs
*If you don't have a GHD you can do toes to bar, or kettlebell overhead sit ups.
For the second part you're going to do, 10 double kettlebell snatches, then 10 overhead lunges with both kettlebells, then 9 and 9, 8 and 8...
