The impact of exercise on our energy levels can be sorted into two camps – short term and long term. While you might feel more awake and alert after just one workout, exercising regularly over an extended period can offer additional benefits for your energy levels and how you feel.

Short-term energy benefits of exercise

There are several reasons why you might end up feeling more alert after a workout, the first being the impact that exercise has on your circulation.

“Exercise increases blood circulation, delivering oxygen and nutrients to cells which can improve alertness and reduce feelings of fatigue,” he says. “Additionally, exercise prompts the release of endorphins – natural mood elevators – providing a quick energy and mood lift.”

Long-term energy benefits of exercise

The long-term impact of exercise on energy levels is perhaps the most impressive. By building your overall fitness, exercise helps your body to work more efficiently and experience less fatigue, Herman explains.

“Over the long term, regular exercise can significantly enhance energy levels by improving various physiological systems,” he says.

“The increase in cardiovascular fitness enables the heart to pump blood more efficiently and supply oxygen to muscles and organs; this increased efficiency reduces fatigue during daily activities.”
