Kids today are mostly unchallenged....and that is fantastic news.
Society has progressed, and life just isn't as physically demanding as it used to be for kids. No wood to chop to keep the house warm, no milk buckets to carry.
But there's a sacrifice that is being made by having made so much progress over the last 20-50 years - and the physical strength and health of our kids is at the top of the list.
And because the vast majority of kids - even those who play year round sports - are MUCH weaker physically than they are capable of - there is an enormous opportunity for improvement for those who ACTIVELY improve their strength and speed.
