Thank you to our new Probies who took it upon themselves to improve our fitness program by custom building a jump box for each station. The dimensions of each box are 20″X24″X30″, which means you have 3 heights to choose from.
So why not try it out with a little something like this (taken from crossfit Vacaville North 7/25/11):
7 rounds:
9 push ups
12 Knees to Elbows (hang from bar, bring knees to elbows)
9 box jump
*if you want to make the push ups harder, lift your hands off the ground when your chest is on the ground to ensure full range of motion.
Enjoy and post your times and comments to the comments link

* I did hands off push ups, but on the knees to elbows my feet hit the ground every time, which probably makes it easier but that’s all I could manage with short pull up bar.
* Box was 24″
Ford-17.30 I was never able to get my knees to my elbows (I know weak huh?) the box was at 24 inches.
Williams- 12.30 as RX’d
