Filthy Fifty

Because of space considerations, I started in the middle of the sequence of exercises, so my filthy 50 looked like this:

50 pushpress 33# (unbroken)
50 supermans
50 wallball 12#
50 burpees (slow but steady)
50 doubleunders (unbroken)
50 box jumps
50 jumping pull-ups
50 kettlebell swings
50 walking lunges
50 knees to elbows (verrryyy ssllloooowww)
Time: 28:04

After the first five, I can only do like two knees to elbows in a row. I will practice what I think is the trick to stringing them together without the extra swing and without stopping so much. I think it has to do with the chest, in the same way you push your body back away from the bar at the hollow portion of the kipping pull-up.
