TNT has always been our acronym for Tumbling and Trampoline. Funny it’s like the dynamite TNT because, we actually exploded with new heights thanks to the invention of the Trampoline, springs, and a straight floor we call Power Tumbling. A division of Gymnastics but, if you ask a born and raised power tumbler and trampolinist if they did traditional gymnastics. They will say, No.
Professional Trampoline, Double-Mini Trampoline, and Power Tumbling floor are the 3 events. You compete by age and level. Girls and Boys do not Compete against each other.
Trampoline You begin by teaching how to land on feet, back and belly. All beginner skills. To twisting and rotating skills. You learn the 10 contacts needed for competition or how to put together a traditional routine.
Double-mini is learning the feet, jumps, and 2-3 contacts on the trampoline with all the same basic beginner trampoline skills minus using the belly or back. Then will come the amazing rotating and twisting skills.
Our Floor is unique as in we go from 5-8 skills connecting with much needed power and force to remain the height needed for elite rotations and twisting. What makes are floor unique is that we are no longer on springs. We moved into slates and now they tumbling on very springy Fiberglass rods.
Trampoline now goes to the Olympics today since the induction in 2000. The Double-mini and Power Tumbling floor have world competitions now on annual basis.
The inventor of the Trampoline and its founders of the United States Tumbling and Trampoline association. Georgia Nissen and his coach Larry Griswold we have much to thank. They grew an invention that became and still up and coming an amazing sport to do and watch. Now we move into the next generation of the Trampoline and Competition. It is called FreeStyle Trampoline and is becoming the action sport. Check out the Freestyle Trampoline Association. Tumbling Boulders will be recruiting athletes and beginning this competition in 2026.

Travels from Hawaii at 12 to performing in the Waikiki Mall, and ironically here to Vegas when I was just 13 for National Team Trip to watch opening of Cirque. Trampoline has became more popular and in so many backyards. Let’s not forget where it came from… a man who was a gymnast who wanted to fly. You can read his book and learn the concept that came from Trapeze Trampoline within the USTA; an organization has consecutively competed trampoline based off it’s founder longer than any other organization running today. The coaches I had were part of the beginning of coaching and competing trampoline. I take that with great pride to show case my athletic history on a trampoline and the specific trampoline coaching I received. Glad to see the induction to Olympics in 2002 the year I graduated High School.
10 years of competition with U.S.T.A. under Hall of Fame Coach Paula Grigsby’s is something I am absolutely proud to be able to say. I’ve learned to be a better Athlete, Coach, and person because of her. She’s more than just a great coach to many. My love for this sport has made a full circle. It exudes when coaching young athletes who want to learn the art of Tumbling and Trampoline’s. Recreational or Competition, your child will learn skills when tumbling and jumping at Tumbling Boulders gym.
