At first glance, the roots of a tree only benefit
At first glance, the roots of a tree only benefit the tree to which they supply, however on closer examination the roots help create a whole ecosystem for which lots of organisms benefit…they break up the soil, draw minerals from deep down, and prevent soil from being washed away so smaller plants can grow.
This is the same with movement practice. By learning one movement we feed other movements, things that once seemed impossible become easy. Learning to perform techniques on Olympic Rings is an example. The practice applied correctly builds strength to be able to do so much more…core stability feeds other movements such as handstands, straight arm strength builds better crawling patterns. Shoulder stability helps protect against injury. The skills translate to so much more.
This is the advantage of movement based training that a lot of weightlifting methods miss out on….learn to bench press, and you are good at bench press, and not much else, use machine weights and you’ll be weak when the machine isn’t there. Learn to move well and it will feed into every aspect of your life.
