Now that the colder and darker months are here we must make sure we stay safe when exercising. Whether it’s in the morning or at night make sure you have reflective wear on if you are on or near roads; if you’re cycling don’t forget your protective gear too. Exercise can increase your mood which will help during the winter blue months.
Make sure you wrap up warm. Although you may feel warm while exercising wearing the right clothing can help avoid getting colds and flu.
