Dumbbell

A blonde woman with green eyes winks and smiles while wearing a black tank top, followed by a close-up of her midriff, then a black-haired woman with green eyes smiling with her arm raised in a light blue tank top, followed by a close-up of her back and pink shorts, then a brown-haired woman with a determined expression in a blue tank top, followed by a close-up of her torso in a pink sports bra, all set against a blue background with large Japanese characters.
