The legs are literally the foundation of your ultimate neck pain, back pain, and sciatica relief strategy. I have started with stretching and walking, now it is time for more! This is a remarkable thing, that I am even able to speak to you about a workout I am doing for any part of my body...but especially the legs! br br I must begin with machines rather than squats or lunges because having suffered with neck pain, back pain, and sciatica for many years, it allows for the most control and a gradual approach.
