I feel there's a mistranslation somewhere because both Silverman and Ganman had "Earth" Dumbbells.
Huh, you're right,
@Questionable91, Turns out Ganman's dumbell was the 土 or Land dumbbell and and Silverman had the 地 or Earth Dumbbell. Those kanji nearly have pretty much the same meaning 'cept 土 is for actual soil and 地 is for the ground and Earth in general, especially this case since Goldman's dumbbell's the Heaven Dumbbell, so I guess Ganman's Dumbbell would be the "Land Dumbbell."
Thanks for pointing this out.
