If You Work Out Too Much, You’ll Burn Less Calories

The more often you exercise, the more calories you burn, right? Not quite, finds a new study. Working out too much can actually make you less active during your non-workout hours—walking the dog, running errands, playing with the kids—resulting in fewer calories burned by the end of the day.

You heard that right: If you work out too much, you’ll actually burn less calories overall.

According to a recent study, 72 women ages 60 to 74 were split into three groups: women who strength trained once a week and did aerobic activity once a week; women who strength trained twice a week and did aerobic activity twice a week; and women who strength trained three times a week and did aerobic activity three times a week. Each workout took about 40 minutes.
