The Grassroots Fitness approach to properly training children is by challenging the child’s balance, coordination, strength and flexibility in a manner that creates success for each individual. In this specific prepubescent period of the child, focus will be placed on strength, energy system training and dynamic flexibility. Static flexibility training is introduced later during the onset of puberty (12 years of age), at which point flexibility will slowly start to decline. Programs can be tailored to a specific sport but only after the basic movement patterns have been learned and demonstrated properly.
