Or will you always be limited by physical capabilities?
Let me try and explain what I mean, I'm going to use my DS as an example.
DS is both underweight and small for his age. He is 10 and weighs 3st 10. He plays a lot of football and is very fit, never out of breath, he's a good runner. But I've noticed that the boys in his class that are a good bit taller than him always have that physical edge, they'll beat him on sports day etc.
So do you think it's possible, if you train hard, to be quicker than your peers who have the physical edge. Or are some body types better at sprinting while others are better at long distance running?
Do you think it's possible to tell yourself I'm going to train to be the best at this (insert anything here) and work at it until you are. Or are some people just natural talented in some areas?
