I don’t know about you, but music plays a key role in my workouts: fatigue decreases and the enthusiasm grows with energy, that’s why I don’t give up my favorite soundtrack even when I run or, more frequently, I fast walking in the park.
My workout must have are my smartphone and my armband Wing by Fonex, which allows me to listen to music while on the move; what makes it really comfortable is the fabric of breathable spandex band (not to be underestimated because it is worn while doing sport) and clamp hold earphones.
The music app that I recommend is undoubtedly Spotify: create your sporty favorite playlist or choose from those proposed by the same app … stay in shape will be easier than you think!
