get one of the ipod holders that go on your arm, or just ducktape it on there or something
Well, in PE I would put my phone in between my waist and boxers on the side.It's surprisingly stable there...but you should run a little and get a little sweaty to ensure it doesn't slip. Or you can hold it like I do too.
I have a walkman
I have a phonograph
That's exactly how I broke my first iPhone, lol. I was doing sprints and it slipped through my pants, unhooked from the headphone Jack and shattered the screen.on the ground, lol.
