Hi Walker,

Step jab, snapping it etc . elbow tight to body. Guard in right place when throwing it. And yea, a ton of repetition.
Good advice.

To put it in a more systematic manner, the first step in improving your jab is by learning and utilizing optimum body mechanics. Youngblood touched upon it briefly but nicely. Once good form is developed, the second step is working on accuracy. The third step is working your timing in application. The fourth step is by improving your muscular endurance in application. The final step is putting it all together in sparring in gradient levels.

I'll expound on this when I have more time. Until next time, take care...

Happy New Year to you all!!!

Best Regards,
