Is Running Better than Walking for Weight Loss? Here’s What a Certified Trainer Says

The Science Behind Exercise Timing and Weight Loss

Do Weight Loss Shakes Really Work?

The Benefits of Morning Exercise

Might Help Your Body Burn More Fat

One small study with only male participants found that those who exercised in the morning before breakfast burned twice as much fat as those who worked out after breakfast.That’s because when you exercise while fasting, you have lower insulin levels, which helps your body to burn more fat. These findings suggest that morning exercise before breakfast can help your body use fat as an energy source andsupport healthy weight loss.

May Help You Be More Consistent

Mike Masi, CPT, a certified personal trainer at Garage Gym Reviews, says, “Morning exercise makes it easier to stick with your routine when you start your day with it. When waiting until later in the day, other obligations can come up that can get in the way of working out, or you may feel too tired from the day. You can plan to work out in the morning before you need to do anything else.”

May Improve Your Mood and Energy Levels

Physical activity stimulates the release of endorphins, neurotransmitters that help alleviate stress and anxiety.Additionally,exposure to natural lightduring morning exercise can regulate your circadian rhythms, leading to better sleep quality and overall mood.Doing your morning exercise outdoors or using bright indoor lighting to simulate natural light when possible helps you reap these benefits even more.

May Support Your Weight-Loss Goals

That said, the timing of exercise alone isn’t a guaranteed solution for weight loss. Maintaining a balanced diet and consistent exercise routine are crucial for achieving your weight-loss goals.

The Benefits of Afternoon/Evening Exercise

May Improve Your Athletic Performance

Research suggests that physical performance peaks in the late afternoon or early evening.This is because your core body temperature is higher later in the day, your muscles are more flexible, and your handgrip strength is higher. As a result, afternoon or evening exercise may allow you to perform better during workouts, helping you burn more calories and lose weight.

“In the afternoon or early evening, your body is more fully awake and flexible. This can lead to more calories being burned either through a higher intensity or being able to work longer,” says Mentus.

May Increase Your Muscular Strength

While morning exercise may help reduce abdominal fat, afternoon exercise may improve muscular performance in women, per a small study.Other studies have observed that participants who exercised in the late afternoon experienced more significant improvements in muscle strength and power compared to those who exercised in the morning.

Everyone’s schedule, preferences and body responds differently to exercise timing. For some, early-morning workouts are energizing and can set a positive tone for the day. Others may find that exercising later in the day helps them unwind and de-stress after a long day. That’s why it’s essential to experiment with exercising at different times of the day to see what works best for you and your lifestyle.

Here are other personal factors to consider, according to Masi:

The Bottom Line

The best time to exercise for weight loss depends on your preferences, schedule and energy levels. While morning exercise may help improve metabolism and mood, afternoon or early-evening workouts can enhance athletic performance and muscle strength. Ultimately, find a time to exercise that you can stick to consistently. Pay attention to how you feel during and after workouts at different times and choose the best time for you.
