TRAININGMASK Training Mask 3.0

I bought this for a friend that's training for her first marathon. She's used it twice so far in running and in conditioning (Body Pump). She said it definitely helped and will continue to use it. Here are her thoughts: "When wearing it I was more aware and cautious of my breathing. The second time I wore it I ran the first 3 miles on half the setting again and ran the last mile on the hardest. I would not encourage anyone who does not exercise regularly to start in the middle. My recommendation - start low and go slow. It's a great device and I would encourage anyone who wants to take training to another level to try one."

Worth the money, works just as it should

The small is way to small if you have a big chin like me

Helped with stamina but it hurt around the ears. Not that comfortable.

Fits so nice and works quite well

The delivery was wrong. The mask works for a bit but if you’re training for a while, mine starts making a pop sound every time I take a deep breath and makes it really easy to breathe, which defeats the purpose. I thought it would be more challenging but it doesn’t really work for me, not sure if it’s just mine or if it’s only meant for 20 minute exercises

I love this mask, one big reason is you don't have to change anything out like with some other models out there. I use this in conjunction with something called PowerLung (green one) and have been able to train on pretty flat surfaces and then compete and PB in many higher altitudes and 100+ mile bike races...and with all of that you obviously just feel very fit from an every day standpoint as well...highly recommend

I have both the 2.0 and 3.0 versions of this mask. I've used the 2.0 version for many years now. While the 3.0 version is simple and easy to use, the 2.0 version can be made to be more challenging, reversing the flow membranes and using the one-hole plugs. The 3.0 version is a good idea and would be a great challenge for most people, but just cannot be made as challenging as the 2.0. I was looking for more of a challenge and more comfort wearing it. The material of the mouth and nose mask is plastic and is very uncomfortable to wear for too long. It rubs the bridge of my nose raw. It seems they should make one that conforms to the face and is also softer.
