does changing weight categories for various competitions exist in oly lifting? Like in boxing where the same person can have different won titles as he goes trough different weight classes?
is there any recorded case of a lifter setting records before or after a weight category change?
how would height and length of the limbs affect how feasible this is for a human male?
Can the correct type of fibers and technique make fat/muscle weight indifferent for lifting?
