The bulk update request #2566 is pending approval.

create alias toned_female (582) -> athletic_female (13964)
create alias toned_gynomorph (8) -> athletic_gynormorph (0)
create alias toned_muscles (115) -> athletic (63194)
create alias toned_body (171) -> athletic (63194)

Reason: toned has been moved to athletic so it's reasonable to move related tags to the existing variants as well.
the latter two suggestions are best placed in athletic I believe.

there is some other tags related to this, but I'm personally undecided on how they should be handled.
