Looking to improve your health but don’t have much free time? Lifting weights once a week may be a solution. In a six-month study, 92 healthy adults ages 65 to 75 were randomly assigned to do supervised whole-body weight-lifting once, twice, or three times a week. Another group did no training. Body fat and LDL (“bad”) cholesterol dropped significantly for participants who lifted weights three times a week, and HDL (“good”) cholesterol levels rose in all three exercise groups. Moreover, individuals who started out with higher levels of blood pressure, blood glucose, and body inflammation improved the most in those areas after the training, regardless of how often they worked out.
