Your Body Clock May Enhance The Benefits of Exercise, Study Finds

A new study found that exercise may work better when timed to a person's chronotype, or natural body clock.

People at risk of cardiovascular disease who trained at matched times saw bigger gains in blood pressure, aerobic fitness, blood sugar, cholesterol, and sleep.

The effect was strongest for clear morning types and evening types, while intermediate chronotypes benefited less dramatically.

Researchers say the results could help personalize workout timing, though exercise is still beneficial at any time of day.
