Is the armband piece elastic so that it stretches with the flexing of you muscles?

No, it's neoprene and has a little flexibility, but its very limited because the velcro strip is fastened to it.

It does stretch and has two places to attach the Velcro. I am pleased with mine. I can fit my phone in it without removing from the case.

It is an elastic band. I do not really know if it works because I only bought it as a stage prop.

Yes. The clear rubber case and the arm band are one piece (and the arm band is adjustable).

It has elastic all the way around, which means it stretchs very well. And holds on & doesn't move.

The chest band has elasticity. I don't think you should have a problem because you can adjust it and on top of that it streches.

Yes it does stretch. As long as you don't require GPS, this unit would work just fine in the gym.

Yes it comes with an arm band that is lined with little rubber bumps to hold it in place. I found the lining hot and uncomfortable. But that's a personal preference.

It doesn't keep it from fully flexing. There is a Velcro strap at the bottom near wrist that you can tighten as you need for support etc. I'd still think some flexing could happen though.

I believe the arm band can fit any one purchasing it. It has a lot of room to stretch

It's stretchy! Has an elastic band. I have a rectangular garbage can that I use and it fits great.

The material is stretchable, and flex able enough to extend with no problem.

the band is elastic, and also has Velcro so that you can adjust the length of the band

yes it fits fine its that it flops around the band part while you exercise because of it being made of the stretchy plastic.

Yes. The band is elastic so many sizes could be used. I love mine and get asked about it a lot.

No, this material does not stretch. It is made of nylon webbing, no elastic.

Yes. It has a little elasticity to hold it in place too. I'm very pleased with the fit.
