The o2 Trainer

[Slick8]

This has been popping up on my IG feed and today I caught him on a Joe Rogan link on the gram.

Has anyone tried this and if so, your thoughts.
It's inexpensive enough to take a shot on myself, just hoping for some first hand experience.

No personal experience. But a weak diaphragm is not why anyone is out of shape. Gimmick. Even if you are at sea level just get out there and get in shape. A week before my first mountain hunt I ran a 2:36 marathon at 400ft altitude. Lived at 600ft altitude. Hunted at 6000-8500ft altitude, kept up with the local guys easily.

It's very similar to training mask.
Or that's what one was called for a bit.
Seems a lot of guys were using them well before they were being marketed. Several guys use them and swear by them. Bas gets behind some hood products so definitely worth a try.

Pass.

If you're going to work your lungs do it without restriction. It'll be more effective.

Yup, I've done enough reading to call it a pass as well.

Hitting various ways of cardio not just the treadmill or elliptical.

Gimmick.

There's a reason why people "live high, train low"....and that ain't it.
