Many people complain of a lack of energy, which can result in feelings of unmotivation and a reluctance to exercise. Quite often this lack of energy may suggest that your body requires some carbohydrates as a fuel source to support your exercise regime. During intense, prolonged exercise the consumption of carbohydrates is recommended to provide you with energy and to enable you to perform at your best.
Pre workout supplements are a further source of energy. Many of them contain stimulants such as caffeine that will provide you with an abundance of energy, both physically and mentally.
