I always knew of competitive weightlifting... And I always considered it a sport. Often when I was a youngen, I would flip through the channels and see big fat men throw weight over their heads followed by a cheering crowd.
Basically everyone I speak to don't think that weightlifting is a sport. What reasons are there?
It has everything a sport has in my eyes...
It tests ones skill, technique, physical capacity (in this case, strength), competition... The only thing I can think of that it is missing is team work... BUT I know for a fact that PLers have lifting partners who work together for the same goal. I would consider this team work.
