Welcome to DV!

I can ALWAYS glide in my dreams, I don't fly or jump of a building I just jump over something and can glide through the air for miles.
This in itself might be considered a form of dream control. I have a similar flying style; I just sort of will myself through the air, and it doesn't take a lot of effort, although trying to control how high I go can be a pain at times. If you want to punch or kick but feel too weak, maybe it's similar to wanting to fly but not feeling like you can. In dreams it's the thoughts that count, which can either help dream control or make it worse (if you think about what you don't want to happen, it might happen). Try willing yourself to be able to punch, the same way you will yourself to fly.
