Here is a punch combo made famous by Mike Tyson that shows how to change levels:
- Assume a short range boxing stance with your hands up in defensive guard (or peek-a-boo technique)
- Keep your knees bent and your center of gravity low
- Begin combo by delivering a Rear Hook to the body
- Retract your punch and deliver a second consecutive Rear Hook to the body
- Continue the punch combination by throwing a Rear Uppercut to the head
- Finish off the punch combination with a Lead Hook to the head
