Watch 30 Minutes to Fitness Your Healthy Back (1970) : Full Movie Online Free In addition to targeting your back, these exercises also strengthen your core, open your hips and improve your flexibility. They're designed to help you do everyday activities with comfort and confidence. Kelly's well-planned sequencing makes them easy. First, she includes lots of between-move stretches (e.g. a "superman," then a stretch, then a modified "superman"). Second, she maximizes results by combining complementary routines (e.g. pairing a pelvic tilt with a torso rotation to strengthen your back and loosen your hips at the same time). It's all taught in a straight-forward, "fitness style" manner — not dumbed down or "medical." Note: the second workout is re-edited from the first.
