This Is Why Walking Isn't Helping You Lose Weight, According to a Trainer

Putting your sneakers on is half the battle, but putting purpose behind your steps is what's going to make the difference. Not sure what that means exactly? The American Heart Association (AHA) recommends a minimum of 30 minutes of moderate-intensity aerobic activity for a minimum of five days a week. "In order for exercise to be considered moderate-intensity, breathing should be heavy and holding a conversation should be difficult," Kelly explained. "One way you can track intensity is with Rate of Perceived Exertion (RPE)." On that 1 to 10 scale, you should feel like you're within the 4 to 6 range, he said.

As the AHA says, 30 minutes should be the minimum time spent working out. If you don't have a half an hour to exercise all at once, try splitting that time up. You can still experience health benefits by dividing your workout time through the day (before work, your lunch break, etc.). But make that 30 minutes your starting mark, and work up from there.

You want to keep your body on its toes when it comes to what movements you're going to make next. Walking at the same pace can get your body into a routine and put results in a slump. "It has been proven that High Intensity Interval Training (HIIT) has shown to have health benefits and can contribute to weight loss," Kelly said. "In terms of walking, this can include walking at a brisker pace for a short distance, slowing down for a period of time to recover, then repeating for a desired distance." You can also try alternating the types of walks you take. One day, go for short, brisk walks, and the next, try longer, slower ones.

To go along with walking at the same pace, it's not the best to walk the same exact route every day. Your body gets used to it and doesn't get the chance to be challenged. To counter this, try switching up your route. Go for that hill-heavy route in your neighbourhood one day, and stick with an even path the next. Kelly noted that this also keeps you engaged in your exercise so you don't get sick of working out.

Since walking isn't a high-intensity workout, you're not burning as many calories as you would with other exercises, such as running. How many calories you need to lose weight is unique to each individual, so be careful not to overeat just because you worked out. While you are burning calories by walking, it's easy to think the amount is greater than it is. "Creating a calorie deficit through nutrition and exercise will lead to weight loss," Kelly said.
