There's a world-wide crisis regarding women not exercising enough — and Muslim women are one of the main groups of concern. Because of religious rules regarding modesty and dress, many Muslim women feel that embracing their inner Sporty Spice is just not an option. But change is in the air! A new organization in London, the Muslim Women's Sports Foundation, arranges classes for Muslim women — from soccer to kickboxing to yoga. In Birmingham, England, the Sisterhood Games allows these women to get all fierce and competitive and scary and revved up about whupping ass (or doing downward dogs, whatever) without feeling that they're breaching any of their religious tenets.
