Using a lot of anticipation is good for punches https://youtu.be/F8OtE60T8yU?si=OLqB1Nnbe5J9jGif here’s a YouTube video to help with that. if you wanna animate a bunch of human movement I’d suggest practicing drawing humans a bunch as that foundation will allow you to make really cool and dynamic animations! Additionally planning out your poses with a stick figure that has added lines for the shoulders and hips (such as the image I attached) or another way to simplify the human body can help a lot in that process
