The CrossFit Open workout 13.2 is on the forefront of many peoples' minds today. The three movements required are relatively basic in theory but often turn out to be significant psychological hurdles for those facing them. The bar, weights, box and onlookers are all potential obstacles in this 10 min AMRAP:
5 Shoulder to Overhead
10 Dead lifts
15 Box Jumps
At some point earlier in the day, set a timer for 10 minutes. Sit somewhere where you will not be disturbed either quietly or with your favorite music playing. (use the same play list that you will use during the competition if possible). Visualize the entire WOD. Close your eyes, what are you wearing? What does the gym smell like? Get your head into the moment. Take yourself through every rep. This is the place to practice perfect form. As the 10 minutes tick away feel your body start to fatigue. Can you feel it? Good, It's all in your head, push through it.
Perfect practice makes perfect.
