Has anybody tried these? I just ordered a Silent Mammoth... which is essentially a coat hanger bent all fancy. It arrives in a few days.

Anyway, anybody have any experience with these sorts of things? I went with this one purely because its metal and I don't want to have some ten-use plastic to recycle if this whole thing leads to improvement.

I don't have sleep apnea but I do think my cute button nose could use a little opening. :)

this past summer, I started biking quite a bit and part of my route involves lots of hills and so forth. It was painful af the first few months, not gonna lie.

although, now, my legs muscles have grown quite a bit (didn't expect that) and I am quite happy with my muscular endurance, although there is still room for improvement obviously.

However, oddly as it sounds, my breathing is still off. As I bike up the hill, I feel heartbeat go up quite a bit and my breathing becomes quite laborious and I wind up taking quick breaths with my mouth aka panting. If I try to do it through my nose, I quickly feel like I am suffocating like I can't get enough air.

In the beginning, this made sense. I was out of shape and all that.

But summer is over, my legs have adapted but I feel like my breathing hasn't. when I am going up a hill, I still feel the need to pant and breathe through my mouth and take short breaths.

Is this normal? that I would have to pant even after 3-4 months of this kind of exercise everyday. I figured my lungs or whatever would get used to the biking route I am taking by this time.
