Earlier in my career I taught fitness classes on a regular basis. I remember loving getting new music to play and seeing how excited participants would get as well. You could feel the energy go up, see smiles on faces and people truly enjoying the experience. Then I found a study that showed when people added music to their workouts that energy expenditure went up by 10 per cent. These days I can’t even go out for a run anymore if I forgot my headset. Music is what gets me going and keeps me going. I have created whole playlists to get me through different types of days. Long run playlists, hard runs playlists and then some heavy metal for lifting weights.
