I looked at a number of Muay Thai development programs. I'm so glad I chose Nak Muay Nation. Founder and Coach Sean Fagan clearly has a passion for Muay Thai and sharing his knowledge. He's genuine, humble, very skilled, and motivating. I am following the Heavy Bag Blueprint 2.0 (HBB 2.0) program and seeing continuous improvement in my technique and power. It is proving to be worth every penny and then some. I'm 64 and have always been into fitness but this is taking my fitness, flexibility, and coordination to new levels. I signed up for the program about 4 weeks ago and do a workout 4 to 5 times per week. An unexpected benefit has been feeling better with life in general; family, work, energy, productivity . . . I highly recommend this program or one of the other programs offered by Nak Muay Nation. Once I've gotten through HBB 2.0, I'll purchase the next program that makes sense for me. Follow the program and you will see positive results. BTW, I sincerely mean every word said above; this review is not endorsed in any way. I truly believe in the program.
