Well, i have a little problem with my core muscles strength/stability in one arm push ups. I believe that i can push much more with my arms and chest but i can't create a proper body tension.
In basic push up position i feel a lot stability, but when i lift e.g. my left arm up (so that is now one arm ps position) my '6-pack' muscles immediately SLIDE from centar to right side.
So when i press up there is a lot of Twist motion in my trunk..
My questions is:
What kind of 'core-pattern' is included in one arm position? (anti-flexion, anti-extension, or anti-rotation)
And what is actually my problem, is it maybe a lazy obliques ?
