How To Keep Your iPhone Safe At The Gym

Question

I have a problem with the Otterbox Defender (or more like a worry).
Here is my  worry.  I like to use my iPhone at the gym.  I also have an iPod touch.   I have used the iPod touch at the gym, with no problems (it has a very  thin rubber protector).
I prefer the iPhone because my gym lacks  wi-fi, so I can't get pandora.  Here is the problem.  The Otterbox is  not too bulky, but more bulky than the iPod touch.
So when I do a couple of exercises, with the iPhone in my pocket, I get nervous.
For  instance, say I do a dumbell exercise (curls), well the DB comes close  to contact with the front/side of my leg where the iPhone is in the  pocket.
If I do a dumbell bench, same problem, you begin with the DB in your lap, right next to the phone.
The biggest is when I do deadlift, because again the bar almost grazes the front/side of my shorts where the iPhone resides.
Now  so far, no problems, but this makes me very concerned.  I am worried  that I am either going to knick, hit, or drop a DB on my lap with the  iPhone in my pocket getting touched, or the deadlift barbell will hit  it.
So I have a few questions......
1)  Am I being a worry busybody or is this really playing with fire?
2)   What do you all do when you workout in the gym (lifting weights, cardio  is no problem, very safe).  Do you keep your iPhone in your pocket or  do you have/recommend an armband?
Most people I see in the gym have  it in their pocket, a few use bands...so that makes me thing perhaps am I  just worrying, but I dunno.
3) Do you recommend an armband, or  is the ottorbox going to protect it just fine if I hastly hit the phone  in my pocket with a barbell or dumbell?
4) Or if I had the Griffen defender, would I be all set even if I drop a 60 DB on myself!
***Note to mods, I decided to make a separate thread for this topic, instead of putting it in the "protection" or "gym call disable" one because this is a larger question, and a very important one.
I felt if I put in one of the prior ones, already a few pages into it, this would be missed, and for people using the phone at the gym who want protection, indeed this is a larger, different topic.

Answer 1

Duct tape it to your head.
If you are paranoid that you will smash it with a dumbbell, then get an armband.
