“I love this little device! It improves swimming performance, anything cardio and just basic breathing efficiency for everyday life and for fitness. 10 stars!!! This product really works, I am currently in the military and going to dive school but I needed to increase my breath hold time. Before, I could barely get down and back doing an underwater swim. I would often get very winded and run out of breath fast. I can tell you that after using this product for about a week or so for a half hour to one hour a day, I can now do multiple 50m underwater swims (some holding 5-10lb weights). I don’t get winded as much, and I can now do high-intense workouts (CrossFit and more) longer without breaks. I highly recommend this product, but remember you get what you put into it, so you MUST use this product every day or every other day, minimum. I usually do it while I’m at work, sitting down, or when I am lying down watching Netflix. Find the perfect time for you and use it increasingly every week. I love this thing!!”

Marathon Runner Focus
“This is by far the best product on the market for increasing your lung capacity. I have competed in three marathons since using this product and I have bettered my finish on average from 42nd place to 6th place. I have used a similar product on the market in the past and really didn’t get any results. Thank you Expand-a-Lung!!!”

Triathlete Focus
“Trust me. Get this. My muscles give out before my lungs or cardiovascular system does if you use it properly. I am a pretty competitive age-group triathlete and cyclist.”
Andy
Endurance Training Focus
“If you train with this daily and use it correctly, you will find real and concrete benefits. I used to get out of breath when doing long distance 1 mile continuous swims and 4.5-mile runs. Now, after using this for nearly 2 weeks, I am able to complete 5.5 miles by just breathing through my nose and without gasping for air and collapsing at the end of every run. As for swimming, I can inhale a greater amount of oxygen and exhale with greater strength underwater, all without the feeling like I am being starved of oxygen. After my exercises or in between sets of upper body and lower body weight training, I don’t get winded or fatigued like I used to. This product is by far the cheapest thing I’ve ordered on Amazon, but it could be my best buy ever. At the end of the day, it’s how you utilize the product. Don’t expect to use it once or twice a week and expect to see world-changing benefits.”
