Soccer players are probably one of the most well rounded or even the most well rounded athletes.
I train MT, Boxing and some BJJ, but soccer now as well. Maybe its just me, but it feels like you are training your whole body. The money is also good lol one of my brothers friends plays in the 4th divison (germany) and earns 25-35k per month.
I think Ronaldo could beat Bolt, if the path is "zigzag" ... i know ... i know ... "under the right circumstances"
I think he could be a good mid. distance runner. But he is still extremly fast ... i mean ... he runs on gras, in cleats + uniform + shin guards + shit technique ( compared to sprinters).
