Hello,
All you need for the workout are either weights or resistance bands and a place to do Pull ups.
Using bands is very effective and much easier and more cost effective than buying weights if you do not already have them. Dumbells are what you need and the best to use are fixed weigght dumbells or adjustables like Selectech from Bowflex. You will want sturdy ones because of the movements involved.
The bands work just as good. You can even get the band upgrade kit and use them for the back exercises and then you do not even need the pull-up bar.
hope that helped
