After hours spent pretzeled up in Gomukhasana pose, chances are your muscles will need some extra TLC after class. Foam rollers are great tools for massageing any knots or muscle soreness, and now they're travel-friendly, too. If you're willing to splurge, try the Brazyn Morph Foam Roller ($68). We love how this foam roller conveniently folds flat into your suitcase and expands into a full-size roller that gets the job done.
