Where to put iPhone when Weight Training?

I never really did weight training at my gym, mainly at home. However, I like the barbells at the gym better now (I have dumbbells at home). My weight training has a routine with certain moves to beats in these remix tracks, which I listen to for cues.

My question is. Where do you put your iPhone when weight training? I have no pockets in my pants/shorts, and don't really want to stuff it up my bra. Is it considered weight to place it between the pants and the hips, i.e. Touching the flesh part of the skin, or is it a little gross?
Do people put it on the floor or on the bench if the the wire is long enough? I'm only doing weight training, e.g. Squats, lunges, presses, etc.

Between the but cheeks is very effective. That way as you are working out the constant clinching firms the glutes as well.

I think your best bet would be to getting pockets or something to clip onto your pants or shirt.

By a holder for the phone, you can get them quite cheap, you put them on your arm in the bicep/tricep area (:
It's worth the money if you do alot of fitness!
If you're not wanting to buy one just put it between your underwear and pants band(:

hope that helps!

You can get an arm sleeve for it. I wouldn't stick in in between my pants because that'd be uncomfortable for me. You can also wear something with pockets.
