It was such a nice evening tonight, there was no way I would be caught in a stuffy gym. I took a 2 mile run/warm up to the park and for started with a dynamic warm up. I then got in to a killer workout. This may look easy to the eye, but try it out and let me know if you change your mind.

Circuit 1 
50 walking lunges
10 box jumps (24-32in)
Repeat 3x (challenge yourself with no rest)
