Warm up That Back
There are very few exercise routines that don't stress the back, so give it a little extra attention when you warm up. Stand with your feet shoulder length apart and place your hands on your hips. Bend forward, so your upper torso is bent slightly towards the floor then circle to the right. Keep it moving to the back to do a small back bend and then around to the left. These back circles massage your lower back, increasing the blood flow and warming up critical muscles. Do this for about 30 seconds or so and then switch directions.
Once you complete your back circles, warm up your hips the same way. Stand with your hands on your hips and shift your weight to the right then circle the pelvis around to give the hip muscles a stretch.
