When he is 22yo even with that height it will take at least 3 weeks to get a pop in OD. Train it while he is young then move to skills take pop quick when he is older
Ok please provide me with that infomation.Mathmatically that means your saying age doesn't affect training? If you train one on one when he is 18yo hes driving, handling, JS will improve just as fast as if he is 21? Is that what your trying to say?Sorry i may have misread what you said
