You could say it's weak, or you could say your nervous system isn't properly wired. It doesn't know what and which muscles to use to eliminate or lessen the movement. Many times, n00bs will do kipping pull-ups (for example, ME) and begin from a slightly swinging, to a full on swing because they don't know how to contract the legs at certain times, and cut swinging.
Another thing could probably be because you don't have much hamstring work. A lot of bodybuilders lack hamstring work because hamstring is a non-mirror muscle. Also another thing is you guys will put long time under tension on your hamstrings, but hamstrings are fast-twitch muscle fibers and thus respond best to activities that involve maximal triple acceleration.
last time was trying to do the kipping pull up, you need to get the groove to swing as well, which i failed to do so. swing a while then quit, forearm was f***ed up d

nah never think of that, i can still recall myself doing pullups and i always fail...cannot pull myself up... but since i was doing it on the combination machine thingy, i can climb up to the handles and do negative pull ups though still get laughed by the damn trainers at my gym... but once i was able to pull myself up...the expression of their faces = priceless... i would say the alternate day practice tip did help a lot
nice one! ignore the trainer in gym, 90% of them is dump ass

I forgot where I read it, but it has something to do that the lats and the glutes forms a 'cross wiring' for the back.
You could draw a straight line from the top your right lats all the way to the bottom of the left glute. Same for the other side.
If you contract your glutes properly when pulling up, the lats would have an easier time pulling you up. I guess it's what pizzaboy says... "nervous system isn't properly wired". Instead of contracting the glutes, you contract your hamstrings instead.
*disclaimer, it could all be some crapshoot theory I made up. LOL!

nah, it make sense, if you found that post, do paste to me
again thanks all for clearing my doubt
