Hello there. So, lately i found that i have to increase my activity (i already go to the gym every couple of days) and the doctor suggested that i start run every morning. I have a iPhone 6 and i was wondering what advice you guys have so i can take it with me since it's my source of music. Armband? or that belt bag thingy? Or in a pocket? What about sweat? And the bending? And the shacking from running? Thank you for your help.
