If you exercise regularly, you may have already determined what is the best and most productive time for you to exercise. Once you have a routine established, it's important to stick with it.

However, if you're not consistent with exercise and you find that it's wearing you down instead of building you up, you may be interested in the work scientists are doing in the area of "circadian rhythms," the internal clocks God put in place within our physical bodies.

I've Got Rhythm

Circadian rhythms, the daily cycles which govern certain physical processes, originate in the hypothalamus just above the brain stem. They regulate everything from body temperature and blood pressure to metabolism.

The influence of circadian rhythms on body temperature seems to have the greatest effect on the quality of the workout we have. When your body temperature is at its highest, your workouts appear to be more productive. They are likely to be less productive when your body temperature is low.

Your body temperature is lowest one to three hours before you wake up in the morning, and at its highest late in the afternoon.

Later in the day your muscles are warmer and more flexible, reaction time is quicker, blood pressure and resting heart rate are lower, and strength is at its peak.

Since studies have shown that exercise during these late afternoon/early evening hours produces better results, it would be good to determine what time that is for each of us.

Finding Your Peak Body Temperature

This will take a bit of work, but is worth it if you really want to know your circadian peak body temperature.

1. Record your temperature every couple of hours for 5 or 6 days in a row. Body temps usually fluctuate by 1.5 degrees plus or minus throughout the day.
2. Try exercising during the period 3 hours after your highest body temperature.

For most people, this will fall in the range between 4:00 p.m and 6:00 p.m. If you are an early bird or night owl, the times may fluctuate 2-3 hours on either side of that, so adjust accordingly.

The Absolute Best Time to Exercise

If stress relief is your goal, exercise works wonderfully well. If you're wondering when it's best to train for an upcoming event, it all depends on what time you'll actually be competing. If an upcoming marathon begins at 7:00 a.m., try training at that time of day. The best time to exercise overall? Whenever you will do it!

If you already have a schedule that works for you, "don't fix it if it ain't broke!" For some, first thing in the morning is best, for others during lunchtime, for others as soon as they return home from work and before dinner.

According to the American Council on Exercise (ACE), those who exercise in the morning are most successful in making exercise a habit.

ACE also recommends that if you prefer an early morning workout, "emphasize stretching and a good warm-up to insure that your body is ready for action."

We would add that combining stretching exercises with Scripture from the Bible and prayer (as we do in PraiseMoves) can help make a good habit even better.
