Working on combining body movements with punching is one of the finest boxing tips I can pass on to you.
When boxers do this, and the top guys do it all the time, the outcome is about increased power and increased defensive protection.
If you want to see a great exponent put this type of skill to practice, check out Smokin' Joe Frazier...this was his stock-in-trade.
Here's the video then below are a couple of key points to take away.
Some key points:
- Use your legs to generate the roll, isolate your back. Do not lean forward by using your waist...this is lazy and dangerous.
- Make the 2 skills blend into one
It's really that simple. Do this and short and mid range and adjust the length of your hook accordingly.
