How did he stick you to him ?
In some cases I would say that I'm just not sure. But many times, it was because I was subconsciously using him for support. I didn't know that I was using him for stability (double weighting) and when I moved him I moved my support. This makes you feel like you're stuck (because you're using him for support) and when he moves you fly.
From the students perspective many of these things seem otherworldly, but when you talk to Tim about them, he's quick to demystify what is happening, usually he'll be quick to put it in terms that you can understand, and explain why something felt so amazing.
