After strenuous and high impact workouts like jogging, weight training and cycling, some people suffer from muscle compression fatigue and spasms. If you have experienced these or other issues related to muscle or back pain, you can help eleviate the sore muscles with the a pair of Anti-Gravity Inversion Boots by Titan Fitness®. These rack mounted boots allow you do perform sit-ups and other ab workouts while inverted for extra effectiveness. They are sold as a pair and come with comfortable contoured pads for best fit. Simply hang from a pull-up bar and swing your legs up to easily and securely attach the boots to the bar. Hanging upside down has several benefits, such as stretching muscles, spreading compressed spinal discs apart, and relieving back pain. Check with your doctor first to make sure this is right for you, and be careful when attaching the boots to the bar to ensure you are safely connected. The optimum time for inversion is 30 seconds to 2 minutes to guard against light-headedness due to the change in blood flow.
