can any one say why there is 7 weights ? used to be 10 in past and in Olympic if I am not wrong we had 8 or 9 !!
It's been in 7 weights for ages since 2002 for all major senior competitions including Olympics,World Championships , etc.
London Olympics (2012) was also in 7 weights both in Free Style & Greco-Roman.Beijing Olympics (2008) & Athens Olympics (2004) also had 7 weights.
Sydney Olympics (2000) was the last Olympics with 8 weights. the Games that Alireza Dabir won Gold.
Since 2002 , both Free Style & Greco-Roman were reduced to 7 weights for all major senior competitions. 2002 is the year that Iran won World Championship in Free Style in Tehran. i was there at Azadi and watched the whole thing including Mehdi Hajizadeh's title winning Gold medal in the final night of the competition.
