Why is that?If I want to use the off-side rotation, I can't really use (and don't need) the leg pressure.
1. Power come from the leg - bottom to up.
2. Use body rotation - back to front.
3. Send power through your arm.
1 and 2 are not mutual exclusive but one after another. As long as you do 1 first and 2 afterward, there is no conflict.
It's a simple trade off.
- With off-side rotation, you punch can be more powerful.
- Without off-side rotation, you can punch out your off-side faster.
