Sounds great....would have enjoyed that as a kid.
in one of my lines of work i see too many people who do such programs or routinely go to gyms and injure themselves, with the help of the quick results sales oriented trainers and owners of these businesses.
Injury doesn’t just happen. it’s this ridiculous mentality of over working the muscles repeatedly = torn shoulders, knees, chronic hip, back, neck issues. Many people exercise too much and don’t stretch or let muscle areas sufficiently recover, which is when the muscle growth happens.
People can get a really good workout in as little as 10 minutes 2-4 times a week, avoiding the overly repetitive 30-60 minute current forms of exercise including some forms of yoga can be over time more harmful to joints and muscles then helpful.
Cross fit and whatever “new” thing comes next is all just business hype. Most Trainers I talk with are so brainwashed to sell the exercise they forget a most important need is flexibility/full range of motion. To me, as people go beyond 25-30yrs old, flexibility, range of motion, balanced muscles side to side - front to back are more important then looking super toned but having muscle attachments at joints ready to pop.
Cross fit for kids is crazy, it’s a boon for Physical therapy and surgeons just as kids playing excessive sports is too. It teaches them to prioritize exercise over proper food balance and I doubt it teaches them to stretch properly or enough or how to do other sorts of things to help their bodies have balanced health.
