Run in Mud Obstacle Race Training-3/6/15

Still icy, so no running yet. I am still getting ready for American Ninja Warrior. Here's a good workout in spite of no run...

50 pull ups with leg lifts. Do these in any style. I did:
10 pull ups 
10 alternate grip pull ups
10 chin ups
7 pull ups from straps x 3

6 single leg air squats each leg x 3

Rope climb

20 push ups x 3

L sit lift. Hold for 10 seconds. Repeat  4 x. (Sit on floor with legs extended in front. Put hands on floor at side. Lift body.)

Walk 3.2 miles
