Build a bullet-proof body first, that can take the stress of your sport without breaking down. From General Physical Preparedness to Specific Physical Preparedness to Physical Skills* to Mental Emotional Preparedness (Training Hierarchy Pyramid of CST).
Most sports approach (in Singapore) are training Physical Skills without building a body that can take punishment. Athletes who play at a high level who can't move properly, who are tight, who are weak etc. It's like putting the latest software in an outdated computer. It will crash.
This is why i am a big advocate of Strength & Conditioning. Laymen, you want to get fit, don't "play a sport", get your ass in the gym. It pays bigger dividends in the long run.
*Physical Skills is the old term for Activity Specific Preparedness. But i prefer to use it because it is more easily understood by laymen.
