Wings, pull ups

[JNel04]

i did wide grip pull ups for the 1st time in a while and man do i feel it in my lats. normally i would just do wide grip pull downs but after doing these i feel that they are a must. as far as form goes what is the best way to keep ur body stationary (so it doesnt swing)?

Tightening up my abs really helps me from swinging. As you reach failure, it will be very hard to stop the swing.

concentration (mental) helps to stop swinging. Focus on what you want to do.

But if you're forcing reps, you're gonna swing. I always see guys in the gym doing that, and they're not really doing anything.

Or you could always get on one of those sissy pull-up machines. They're good for pumping out some more reps with good form.
