Are you guys fucking serious?? 20 + reps?? Are you talking about widegrip pullups, or just regular pullups?? If your talking about widegrips, more power to ya. I can only do about 10 on my first set. It pisses me off because I would love to do weighted wide grips, but I really don't think it will be very effective. When I do weighted dips, I can do a lot(130lbs for 10). I guess it's no coincidence that my chest and tri's are my strongest muscles, while my back and bi's are my worst. Especially bi's.
