Rugby players spend a lot of time physical training Compared to other form of sports. I have read the Rugby laws mentioned on this site. It’s a gripping sport which targets the grip strength and the active mindedness of a player. American football and rugby league are also primarily collision sports, but their tackles tend to terminate much more quickly. For professional rugby, players are often chosen on the basis of their size and apparent strength and they develop the skill and power over the passage of time. In modern rugby considerable attention is given to fitness and aerobic conditioning as well as basic weight training.
There really are some sick people out there.
