Almost Forgot

I completed the CrossFit pullup clock tonight achieving 18rounds with 8additional pullups. My previous was 19rounds and 10additional pullups. My grip is what failed me tonight, also the last time I did this I did it at the gym were their pullup bars do not go all the way across there is a big gap in the middle, so I am not sure that my chin was over the bar on all of the reps from my previous attempt, I will count this as my baseline as I KNOW my chin was above the bar on all of the reps.
