The pics with Igor-in his yellow shirt- shows the "tic-toc" drill. For lack of a better name, this is where the partner presses at your hips and neck to get you rocking back and forth on your hips. Go faster and faster until failure.
It opens up the hip joints and trains you to deal with stabilizing while staying relaxed enough so that you don't lose your balance but not so loose that you tumble over. As well, you're dealing with equilibrium issues.
The other pair of photos shows a fireman's carry that you load into back-squats. Simple enough, be sure to load your partner onto the tops of your shoulders and mind your stance. This is a real challenge if you do it as a "box-squat", if you know what that is, just be ready to bail out!
