Another way to do pullups, too: get a resistance band and sling it over something high and sturdy--placing a hook high on a wall will work, if you don't wish to tempt a drapery rod or ceiling fan. Then you pull DOWN, instead of pulling yourself UP. Works the same. Our routine involves a lot of pull-ups, and I do mine on the bowflex, pulling down.

Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.
