Our gym inlcludes TOPS in the daily training for all our gymnasts. The kids with the aptitude for this training are pulled to work higher level skills. Its not a money maker for the gym and ALL the girls get strong. Our gym doesn't charge extra for the training, it is part of ALL girls daily training. I think its an awesome program. We had a a few girls make national A/B team last year and DD is a hopeful this year.
