Thousands of us have started 2023 with new exercise programmes promising to get us fit, muscle-bound and slim. But the latest science of chrono-exercise (sometimes called chrono-activity) suggests that what really counts isn’t what we do, or even how we do it, but when we do it.
Of course, moving at any time of the day is good. But we now know that our bodies and brains change over the course of 24 hours, with chemicals, proteins and hormones ebbing and flowing almost hour by hour. So perhaps it’s hardly surprisingly that a string of new studies suggests that timing our exercise to optimally match our body’s circadian rhythms could reap additional rewards. And that means faster results – and less time in the gym.
