Kids & Teens: Why Summer is the Best Time to Build Physical Foundations
The school year imposes a particular kind of structure on children's time — one where physical activity is largely confined to PE lessons, break times, and whatever organised sport fits around homework and family commitments. It is not an environment that lends itself to consistent, progressive physical development. The summer holidays are different. For six to eight weeks, the schedule opens. The pressure lifts. And for parents thinking about their child's long-term physical development, that window is worth using deliberately.
The case for summer as the optimal time to introduce structured movement is partly practical and partly developmental. On the practical side, consistency is the primary driver of physical adaptation — in children as in adults — and consistency requires time and schedule flexibility that the term-time week often cannot accommodate. A child who attends two sessions a week through the summer holiday accumulates sixteen to twenty training sessions in a block — enough to establish a movement pattern, build initial strength, and develop the habit of showing up before the demands of September reassert themselves.
The developmental argument is equally compelling. Children in the primary-to-secondary school transition years — roughly ten to fourteen — are at a particularly sensitive period for motor pattern acquisition. The nervous system at this age is undergoing significant reorganisation, including the period of rapid myelination — the deposition of the myelin sheath that insulates nerve fibres and dramatically increases the speed and efficiency of neural transmission — that makes motor learning especially effective. Movement patterns established through deliberate practice in this window become deeply encoded in a way that adult motor learning cannot replicate. The ten-year-old who spends a summer learning to squat, hinge, and pull properly is building movement architecture that will serve them in every sport and physical context they encounter. I saw this in my 20+ years coaching golf. Kids in a single summer holiday going from breaking 100 to breaking 80, for non-golfers this is significant!
There is also a psychological dimension specific to summer. Without the academic performance pressures and social dynamics of school, children often approach new physical challenges with less anxiety and more openness. The child who is self-conscious about their athletic ability at school may discover, in a non-competitive coaching environment, that they are more capable than they believed. That discovery — in a structured setting where the coach's job is to find and develop the ability that is there, not to rank it against peers — is one of the more valuable experiences a parent can facilitate.
At CrossFit Chiltern, we run Kids & Teens sessions throughout the summer. The structure is the same as term-time — movement quality, progressive challenge, a community of young athletes who push each other and support each other. If your child has never trained in a structured environment, summer is the natural starting point.
The foundations take time to build. The best time to start is always earlier than you think.
