“We train every single muscle in our body except the ones that deliver us energy, which is absolutely crazy to me. We are way too focused on developing new fancy supplements, but the science is there, it's been there for years"

— James Nestor, author of Breath: The New Science of a Lost Art

The Biggest No-Brainer For Athletes!

If you think this is bullshit, it's because you are doing it wrong. Once I started training using the correct technique in their guide, I instantly felt muscles I had never felt before and started noticing results after only 2 weeks, but I definitely feel like you need to be consistent with this for it to have a major impact

BE CAREFUL its easy to overdo it. You feel motivated and you feel your belly muscles working so much. Did way too much the first time and was way too sore

I bought this for my daughter as she would sometimes feel tightness in her chest while doing certain sports (basketball, track) or just while running in gym class. Since she’s been using it (a couple of times a week at first and then less often), she feels like her lungs have opened up and her breathing during exercises/sports has improved so much. She doesn’t have to take breaks anymore and can endure the entire workout.
