cycling is the most physical sport as it uses all the muscles in your body
Probably swimming, uses most of the muscles and seldom causes harm to player or others.
If you were to pick a sport that focuses mainly on speed training it would most likely be track. Track is great for endurance and it helps build you leg muscles. Track would be a good sport that uses speed training!
weight lifting sport uses the trapezius most.
YES! abs are one of the most important muscles for gymnasts. in fact, I've been told that gymnastics, as a sport, takes the most ab muscles of any sport.
what i think of the sport that uses the most energy in an hour is wrestling and track and field because you use youre whole body with that sport
swimming... i think :)
