Today I came across sex positions that double as workouts. To my surprise, missionary was the first one listed. According to Fitness magazine, you don’t have to let the person on top do all the work. With an equal, opposite thrust from the bottom you can get a core workout. However, to avoid injury, it’s important to thrust with your pelvis and not your lower back. You’ll also get a good butt workout by squeezing those cheeks while you thrust.
Finally a workout regime I can stick to!
