Bubs is head down and has been since about 26 weeks, and I get lots of kicking and punching movements. Over the last couple of weeks though he seems to sweep from side to side (as opposed to full flips), especially when I am driving or sitting down. I don't think he likes being cramped up! You can see him kind of rolling from side to side as my belly changes shape as he does it. He is very active throughout the day, so I have never been worried about a lack of movement.
