Research over the past 10 to 15 years has shown that with proper adult supervision, strength training is a safe and effective method of conditioning for children (sources: Center for Disease Control, American Pediatrics Association).Fitwize 4 Kids Lifestyle Fitness Centers provide specially designed fitness equipment that is made for kids bodies. Each piece allows for multi-joint, closed kinetic chain movements. Research shows that these types of movements reduce the likelihood of damage to developing bone growth plates. The movements also maximize compression forces that increase bone density in adolescents and pre-adolescents. When combined with our low-weight, high repetition resistance program, this equipment allows growing kids to safely build lean muscle mass and reduce the risk of injury.
