Dear inner-thigh fat, I'm so sorry to see you go. Love, yoga. If your inner thighs could use some attention, here are nine yoga poses that'll fire up this. The Rajakapotasana is one of the most effective yoga stretches for inner thighs as it opens up the chest and gives your legs a good stretch. Your inner thighs particularly benefit from this asana. Strengthen and lengthen your thighs with yoga poses ranging from High and Low Lunge variations to the dramatic Peacock Pose.
