For all the people who dont know what a rack chin is its in the video but my question is is a sitting down lat pull down was equal. I think mainly the dc guys will be able to answer best but at the gym today i was talking to a guy who was doing lat pull downs by sitting down and hooking his feet on the seat. he was using a close parallel handle.
When i asked him why he liked those more he said better stretch and more control. Now the point of rack chins is to get a better stretch so i was wondering if this exercise is equal to a rack chin in terms of how effective the exercise is. http://video.google.com/videosearch?hl=en&fkt=536&fsdt=3266&q=rack%20chins&aqi=g3&um=1&ie=UTF-8&sa=N&tab=wv#
