This exercise will improve your core strength, specifically the muscles that support the side of your spine and hips.
Start on your right side with your knees bent. Your right elbow is bent and positioned under your shoulder. Lift your torso and head. Hold this position for 5 slow deep breaths. Progress this exercise by lifting your hips as you press your bottom knee into the floor. Extend the top leg and arm. Take 5 slow deep breaths and repeat 5-10 repetitions. If you notice that one side is weaker than the other, complete a few more repetitions on the weaker side.
