Pierre I would love to see your progression towards a muscle up. I went to the opening of Crossfit Evolution in Longwood today and they had a harness to assist with muscle ups. I of course jumped right on and with a mere 60 lb's of assist voila, muscle up. I am pretty sure that I could do it with less. I didn't try as I am pretty banged up from BJJ this week and really trying to make Saturday and Sunday rest days.
I like your progressive resistance approach and recommended that to my wife for pull ups.
How would you use the same technique to attain a muscle up? I have some ideas but would love to hear it from you.
Sorry for the possible thread hijack.
