B true is right, all you need is chalk. Years ago I used to have trouble just chinning with my bodyweight as my grip would give out. I stuck with it, did extra forearm work, and now deadlift in the mid 400's for reps off the floor then chin with my bodyweight plus a 45lb plate, no grip problems. If you make wraps a staple now, you will ALWAYS need them, personally I don't like being dependant on anything but ME!
