The nice thing about using the strap for pull ups, is that you can do four types of pull ups, by simply changing your hand position.
1) Palms facing out = a regular pull-up.
2) Palms facing each other = hammer-ups.
3) Palms facing in = curl ups.
4) Rotating your hand position out to in during the pull up = the wicked-awesome pull-up.
I prefer breaking my pull-up routine up. I'll often do 10 of each one with a short sprint in between. By the time I'm done, I've completed about a quarter, to a half of what I wish I could do.
You can wear gloves if you are a sissy. I for one wear them because they feel nice on my hands and bears no reflection on my manhood.
