Impressive! I've been doing karate for 24 years and always in a very sports-like life style: free weights, calisthenics, yoga, running, swimming, etc.
Then you see this and feels fresh, powerful, scientific, scalable and well structured.
I will introduce much of what I learn into my katate classes.
Jim Romig's MedBall Athletics is the best medicine ball conditioning program out there! I've seen it grow from a solid foundation to an ever evolving powerhouse. The only thing better is the man behind the program himself. I highly recommend this.
Absolutely the best Medball program out there. Like a 20 minute fight with a Medball. Do it!
