Used this before my morning jog and felt so much lighter on my feet. My chest feels open and the air flows so much easier now.
Finally found something that makes uphill climbs feel manageable. It fits perfectly in my gym bag and is super easy to clean after I finish.
Really helps when I am hitting those long miles. It takes a little getting used to but my endurance feels stronger every single day.
Simple tool that just works. I take it with me on every trail run to keep my breathing steady and controlled throughout the whole route.
I noticed a big difference during my interval training. My breathing is much more rhythmic now and I don't feel as winded by the end.
Takes up zero space in my pocket. Perfect for getting those lungs ready for race day while I am out doing my usual loops.
