For the record: Strength Training before, not after, cardio is better for your heart, reports a study in the Journal of Applied Physiology. Japanese researchers found that participants who lifted before running had more flexible arteries and improved blood flow after eight weeks, compared with a run-then-lift group (who experienced no such improvement). Why? Lifting can increase blood pressure, which stiffens arteries. Running afterward releases chemicals that cause the arteries to dialate and lower blood pressure, says Robert C. Scott III, M.D., Ph.D., senior staff cardiologist with Scott & White hospital in Temple, Texas.
