Lance Armstrong One of the methods he uses to keep in peak performance is chiropractic care. According to his chiropractor, Dr. Spencer, “My job with Lance and the team is to optimize the neuromusculoskeletal component of their training and, in the event of a crash, minimize down time and get them back in the race as quickly as possible. I adjust them as needed and guide them in choices of diet and supplements, which helps reduce the likelihood of injury.”
