My son is 1m76cm and he can jump 1m50cm he wants to know is this good and if not how can he improve.|||That is really good avarage for him. Usually 13 years old guys jumps about 40-50 but his avarege is really good. If u wanna raise his avarege you should work some leg curl with him...|||He is good
Make sure he masters the Fosbury flop
Train a lot!|||well it depends on the person.|||dang he jumps high... i skate all the time and i cant jump that high
