If I'm fresh; 24 strict (no kipping, leg's hanging not raising at top). Approximately every second day I'd essentially do between 150-300 pull up's in a session. Although, at the moment I'm training with additional weight or using a latt pull down machine so I'll be down on those figures. Why do you ask? NB: I train for ice climbing. I ask because I want to see the connection between doing lots of pullups and pullup endurance. I must ask guys, any of you do mountain climbers? Very curious...
