Lunge and Twist
This stretch is great for the hips and waistline. Start in a low lunge position with your back knee on the floor. Press the hips forward and hold for three to five seconds. Then, rotate your upper body across the front leg. Hold for three to five seconds and release the stretch. Perform five to eight stretches on each side. This stretch focuses on opening the hip flexors and tones the core muscles with emphasis on the obliques.
