TOKYO (Reuters) -A dozen women in sports bras and tight shorts stood behind a U-shaped counter at an underground bar in a busy Tokyo neighbourhood, chiselled frames on full display as they crushed grapefruit in unison with their bare hands.
The music blared and neon lights flickered against a hot-pink backdrop as customers at fitness-themed bar Muscle Girls whooped and cheered in a scramble to capture the ritual on smartphones.
