Some people leave their DNA in hotel bedsheets and at crime scenes. I prefer to leave mine on the pull-up bars and kettlebells at my CrossFit gym.
On the menu for today:
Kettlebell snatches (6-6-6-8-8-8)
1-2-3-4-5-6-7-8-9-10 Plyo Box Jumps
It took me forever (7:33) to finish -- mostly because a bunch of my pull-ups were crap and I had to repeat 'em.
