Dashing in can cause some problems...

1. I feel that you should always relax with your movement and keep your body centered and in a good stance(Balanced)

2. Rushing in can cause you to become off balance and get caught with something that could end your day...

3. If you are going to dash in, Dash in the smart way...Lead with Jabs and set up your power, dont just jump in with a power shot....What if it misses?? What you going to do then...

With experience in the ring you learn to become more Ring Mature and as that maturity comes, you will learn that relaxxing with pressure comes natural...
