Guys, I been training for quite a while now. I managed to cut down my weight from 100 to 93 in about 2 months+, currently eating a lot of protein source like chicken breast and brocolli etc.. My questions is, why is it so hard for me to achieve even a single muscle up, am I hitting a wall or something? I can do pullups and chin up easily though, however when it comes to muscle up's, I can't seem to lift myself up. Is there a special technique to do this? The bunch of videos on you tube does not help much. Thanks.

Sincerely,
Daniel.
