@themba990: I'm gonna get me one of those door frame pullup bars so i can do neutral grip pull ups! I too suck at normal pullups. Neutral grip I suck less at. I'll aim to improve on neutral grip and chin ups and hopefully it will translate to normal overhand grip.
Stay away from the cheaper Men's Health door pullups bars, they are made of plastic and bend when exert weight on them.
Maybe look for something metal.
