Standing - Sex Positions That Double as Exercise

Standing

Standing is one of the more challenging positions because often the woman has to allow her partner to lift her in some way, says Britton.
If the man and woman are facing each other, core and upper-leg strength comes into play: if she's standing on one leg, those leg muscles are worked to keep her upright, and core muscles are engaged to keep her balanced. If she's wrapping both legs around her partner, she'll need good arm strength to hold onto her partner. And regardless which one of these contortions she's in, "she has to have stamina if she's standing," says Britton.
If the man and woman are facing the same direction, the same muscles engaged in doggy-style are used: she'll work her core for balance, and her arms can be worked if she's bracing herself against a wall or headboard and using them to help thrust.
