just a recent training session recorded, comments welcome
the chains weigh 20kg each apart from the two small ones which are 5kg. Total weight = 50kg
Need to work on your form. You very quickly start relying on your arms to pull you up and not your back. I don't know how much of a weight room ego you have, but something I did recently was dropping the weighted pullups and going back to the basics. Focusing on lighter lat pulldowns to learn how to full and efficiently activate my lats throughout the motion and worked my way back to normal pull ups.
I'd ditch the chains until you can do bodyweight and look like nate green in the second video here:http://www.T-Nation.com/free_online_article/sports_body_training_performance/things_you_should_know_how_to_do_1_the_pullup
Its an strength endurance drop set. The goal isnt super strict form. Watch defrancos guys doing chain pushup/ pull up dropset, the form is not great. Yes you have to go strict on normal pull ups and normal weighted pull ups, but not a drop set.
Good video, keep having fun
I'm aware of this. I know form fades during a drop set; however, OP only has about one questionably decent pull up in there. I don't think he's ready for these just yet.
