Review on 🏃 TRAININGMASK Training Mask 3.0 - Breathable Cardio Workout Mask for Running, Cycling, and Exercise – Black Training Mask by Juan Wilson

So I've been using this mask for a little over two weeks. The mask reduces airflow and makes the lungs stronger. I started with 3 clicks and the next week I was half closed. Depending on how wet it is, I should open it a little more. I do one mask-free day a week and I feel like I have more stamina and I can breathe better. Well, or of course I can without a mask, but I will say that I can last longer on my cardio, my overall performance has improved. This is just my opinion. I've seen reviews calling it a gimmick, but I've used it and I feel like it's helped me at least feel like I'm getting a little bit more out of my workout. The only problem with the mask is that the holes in the ears are very annoying. They bite my ears, often forcing me to adjust or just pop my ears out of them. The problem is that the mask does not remain airtight. Also, I like to wear a mask!
