As the NHS points out, even a single 15-minute walk can give you an energy boost, and the benefits increase with more frequent physical activity.
Start with a small amount of exercise and then build it up gradually over the weeks and months until you reach the recommended goal of 2.5 hours of moderate-intensity aerobic exercise, such as cycling or fast walking, every week, advises the health site.
Exercise also helps you to lose excess weight, which can take its toll on the body, leaving you feeling exhausted.
“It also puts extra strain on your heart, which can make you tired. Lose weight and you’ll feel much more energetic,” explained the NHS.
