As someone who runs 8 to 10 miles nearly every day, I want you to know that after using The Breather for several weeks, I have seen a definite improvement in my lung power. I can run easier, faster and with more endurance than I had before. I highly recommend The Breather to anyone who exercises, or for that matter, anyone who wants to breath better. Congratulations on a wonderful product.

I am a natural, amateur body builder looking to make gains wherever I can. I have tried various training methods, been on different diets, and I have used supplements, but nothing has helped me make sustained gains as the Breather. Different exercises, diets and different supplements seem to make small, temporary gains, but the Breather continues to improve my performance on a consistent basis. If you consider the on going cost of supplements, and the unknown long term effects they may have, the Breather represents a tremendous value. It's a small one time cost (provided you don't lose it like I did), it delivers consistent, quantifiable results, and above all it's safe. I have tried other gimmicks and equipment that purport the ability to deliver break-through gains. While interesting and novel toys, these gimmicks don't hold up over time. The investment I made in the Breather has rewarded me over and over again. I don't regret spending money on quality equipment that delivers performance. This is quality equipment that delivers results you can see and feel immediately. Perhaps the greatest benefit is the Breather's effects don't apply only to body building. If you want to increase your performance in any sport, or if you are just looking for an easy, safe way to improve your overall health, the best device is the Breather.

One of the best resistive breathing devices to use for forced expiration is the Sports Breather. In essence, the Sports Breather is a small device with a mouth piece and adjustable openings for air to enter and exit. With this device you can increase the resistance in both inhalation and exhalation, which forces the muscles to work harder. Preliminary studies have demonstrated the great effectiveness of this device in increasing chest size and in decreasing waist size. In addition, the Sports Breather helps to improve sports performances, especially in those sports that require endurance.

I believe that these Sports Breathers offer the best value for money and size if any martial artist wishes to complement their existing training regime with increased lung function. As an asthmatic and Martial Artist for over 15 years, restrictive breathing techniques have been invaluable in order to progress within the art. The Sports Breather offered by Sharron was initially bought as a replacement for a competing breathing device, which retails for over 4 times the price and is almost 3 times bigger. The Sports Breather is a smaller, truly portable device and can be left in a gym bag or car to be used anytime. I give it my full recommendation and the level of customer service offered by Sharron is second to none.

I must say after about my first full week of using The Sports Breather on level 2 inhale/exhale I could already feel gains in my over all breathing and ability to not feel winded in my cardio exercises. I run, cycle, swim, and I am now doing flights of stairs for cross-training. I feel great during and after my work-outs now. I log in my stair work-out routines along with how I felt during and after the accomplished work outs; before I purchased the Sports Breather I could do my stair training work-outs but I truly felt that my lungs were working over time and I felt very winded to say the least towards the end of my work-outs. I am adding flights now to my stair training work-outs and now feel I have total control of my breathing...until my legs give out of course... :) I feel like ROCKY!!!" I am still working on the Rocky physic though...

I was very satisfied with my deep breathing exerciser. I am not a swimmer or a jogger. I use it to exercise my lungs because I am very short winded due to lung cancer in 1998. I am a survivor but have some damage and this is the first thing that I can say really helps. The seller was very helpful and followed through with me to make sure it was what I needed.
Thanks much Sharron
