1. Skipping your daily workout
Personal trainers preach the importance of the occasional day off to give muscles the chance to rebuild and strengthen. In fact, for seniors, four workouts a week is more beneficial than six, according to a study published in Medical and Science in Sports and Exercise. The study randomly assigned women between the ages of 60 to 74 to two-, four- or six-day aerobic and weight-lifting schedules. After four months, there were no differences in fitness levels among the women-all increased muscle and decreased fat mass equally. However, those who exercised four times a week burned many more calories in their daily activities than the six and two-times-a-week women. In this case, those who worked out the most had little energy left over, while those who worked out four days a week were reinvigorated. Bottom line? If your workout schedule is leaving you drained and laid out on the couch for the rest of the day, it’s time to cut back.
