What's Wrong With This Picture?

Hummmmm...
There's something missing in this practice session. Can you Taiji people out there see it?
There is no use of "ward off" (peng), and "press" (ji). This is a criticizm that has been pointed out about my current level of push hands by my instructor. I, like these guys, am using my hands too much and not my forearms. They even have their forearms in the exact position against the opponents body at times, and don't use it. As my instructor tells me, if you only use your hands, you are already at the limit of reach. If you plan well and use wardoff with your forearm, you can continue to unfold your arm in a wave-like fashion and really, really extend through the opponent. Secondly, you can press with your palm against the inside of the wrist or forearm as it "pengs" outward for united power of both arms.
None-the-less, this looks like a fun session, at a speed where the student can understand and learn about strategy and positioning. I also do like that when the student pushes him, he grabs the wrist and elbow in the "play guitar" or "raise hands" posture as a counter.
