Breathing Exercise Lung Trainer | (RMT) Respiratory Muscle Training Tool

I use mine 3 to 4 times a week while doing paperwork at my desk, yes it's that easy to use and helps you alot when you do go out and run. Just one word of caution is when people pass by there looking for Darth Vader. I do recommend it for people with breathing issues and smokers it really opens your lungs up and helps with your overall lung capacity. I'm 57 and I can tell the difference.

Easy to use and as advertised. Using it to try and increase my endurance. I felt my diaphragm and stomach muscles a day or two after I started using this, so I know it is having some effect. Will keep using it before bed and before a workout.

Good for the price you pay, small and fits in your hand, easy for on the go

Excellent! Very happy with it. Like it's small size. Easy to rinse off (And, you do have to do that). Use it at least once a day with enough resistance that I can feel it working. I hated that clunky thing they give you in the hospital. Broken ribs and chest injury on the mend.

This item does exactly what it is advertised to do. Expand your lungs. Great for someone with breathing problems.

This was recommended by two doctors. The first suggested it; the second just commented that she was glad I bought it. I am actually aware that my lugging groceries up stairs is going more easily. I am panting and gasping less and am no longer wondering if I should buy a ground-level condo. By way of a personal experience: I have found breathing two counts through the nose and then exhaling four counts through pursed lips when I try something taxing has helped increase my endurance.
