Workout Mask for Fitness Resistance Training Running Breathing Mask,Men Women Adult High Altitude Elevation Simulation Trainer

Great overall. Improved my stamina after one week using on bicycle 5 miles a day

Worn it once while doing spinning for 30min. Took a short while to get used to the breathing. Fits nice and comfortable.

Lovely quality product only thing is I cant find replacement inner disks for it anywhere. So this limits the shelf life of the product. So 4 stars

Does not look good works ok .

Very controllable breathing valve. This mask, hopefully, will help reduce long term blood pressure rather like the RESPerate device.

So I just tried it out today on my bike and oh my God it makes a difference and it’s great that you can adjust the settings as you go along highly recommend buying one

This item is superb , and very good quality. I know it came a bit late but it was all worth the wait .

Ok, it’s not the big brand but the product is very goodGreat looking mask, confortable and gets the job doneWill improve your cardio, has resistance valve adjustable
