Run in Mud Obstacle Race Training-1/17/15

I bought these CFF Pro Series Monster Grip Cannon Balls to prepare for the American Ninja Warrior audition. I hung them up to my kid's swing set (custom made and can support my weight). I removed the swings, separated the hooks from the balls, then hooked both straps and Cannon Balls to the swing chain fasteners. Now I have a few training options. 

I do pull ups by gripping either the straps or the Monster Grip spheres. I can't do monkey bars with the spheres yet, but I can with the straps. Both are awesome.

4 pull ups and rest for 10 seconds x 6

Monkey bars with straps x 2
