<p>I don’t know the mins, all I know is that my son is also tall and thin. At summer seminar, his pull-up score was a joke along with his push-ups. He scored a whopping “7.” He did pull-ups on a pull-up bar ALL summer long. He can now max out on both, so the pull-up bar was worth the money. </p>
<p>He’s still skinny, though.</p>
