Heel Up technical for bass drum.
Please pay attention I have my heel lift up just a bit from the pedal, then I used the ball of my foot as the main muscle to push down the pedal to have the beater strike the drum head. I also use the joint of my foot (similar to the wrist motion) to control and play the bass drum pedal.
I also lift up my leg to have a powerful stroke.
This is a common technique to play rock, pop and most mainstream music as all those genre requires a lot of powerful solid bass drum sound.
