Good for city dwellers and travelers. 1 minute rest in between sets. You will build up stamina and gradually be able to add to your reps. Alternate sets, 1st set of 5 palm forward, 2nd set palms facing you. I do a set of sit-ups between pull-up reps. Also as you progress you may alternate the width of your grip for more complete muscle development. (Set 1) 5 reps, palms forward (Set 2) 5 reps, palms facing Do (4 sets) of each type of pull-up and you are done!
