Better than Altitude Tent?

So, I fractured a few ribs! Who hasn’t??

My DR prescribed me this cool toy to monitor my breathing and force me to expand me lungs and breathe deeper and stronger. (Sounds like a Coach Chad text.)

No, I don’t think this will raise my blood/oxygen level, but it should help me to breath better all the time.

The book “Breathing for Warriors” is worth a look. No gadgets required.
