I saw this video on you tube and I am amazed this guy could improve 4 meters in 1 year in shotput
here is a second video which analyses his throw. Looks pretty damn good to me
What kind of improvements have you achieved in a year?
How many throws can you do per year?
I can see how you can do 10,000 discus throws a year using a net but shotput is heavy so I imagine 20 would be max per year you can do.
