I am starting a separate log to keep track of my pulling workouts, which mostly consist of pullups and chinups. I was working up to a one-arm pullup for quite a while and then got sidetracked from that by finishing my degree, getting a job, having a kid, and moving clear across the country within a 6-month period. No excuses, it's just time to get back on track.
My stats: I'm 31 years old, I weigh about 190 lbs. I've always been better at pullups than chinups. My most impressive pulling feats to date are 22 consecutive pullups and 305 pullups in an hour. All of my pullups are from the dead hang-if they are not then I don't count them.
