In the competition of Olympic weightlifting，the athletes try to lift the maximum (最大的) weight they can. There are special conditions they have to meet in order to compete：body weight，height and strength. The Olympic weightlifting mainly tests the limit of explosive strength (爆发力)．There are not many lifters who really like Olympic weightlifting and the explanation is very simple：they are short of explosive strength. The weights used for Olympic weightlifting are added in kilograms. The order by which the athletes enter the competition is not general，but it is set depending on the event. Usually the athlete with the lowest weight begins. If he/she is not successful，he/she can try later. There is a maximum of three lifts allowed for every competition. For many years Olympic weightlifting was only for men. However，now women also take part in Olympic weightlifting. It was at the beginning of the 21st century that women’s competitions entered an organized professional environment. For women，Olympic weightlifting is more difficult because of their different body structure. However，strength training techniques (技术) are widely and successfully used by women，too. Lots of the athletes who’ve ended up in Olympic weightlifting competitions have started with strength training only to improve their muscle condition and their body power. However，the demarcation line (界线) is not still very clear between power training and Olympic weightlifting. This is how so many lifters have got into Olympic weightlifting competition，even if their purpose was different at the beginning. 小题1:In the competition of Olympic weightlifting，athletes need to be all of the following EXCEPT________.
