Legs in straps have so many benefits. Not only are you strengthening and lengthening your legs to make them lean and strong, you are doing so much more. Legs in straps strengthen your TVA (transverse abdominals), lower back, and encourage the synovial fluid in your hip joint to move to essentially lubricate your joint. Legs in Straps keep your hips, back, and abs healthy. So next time you enjoy leg circles, your body thanks you too.
