Squat Cleans

Warm Up:
3 x 15 sit ups
3 x 15 back ext.
box jumps

WOD:
Squat cleans - sets of 3, 3, 3, 3, 3
Started with 45#
55# on the next set
then dropped back down to 45# the last three sets.

I tried that stupid medium box today and just couldn't do it. Chris piled up the 10 pound weight on top for me then added the thicker 25# weight. It scared me to death. I think I did the first jump without any extras on top, but then when the others got put on I froze. I must have stood there for 15-20 minutes staring at that stupid box and just couldn't make my body move. Don't know what I'm so afraid of. I was so angry and frustrated, but my good friend just stood by my side waiting for me to make the jump and encouraging me. I love my friends but I hate that I'm afraid of a dumb box....a BOX!!!!!
