Review on 🌬️ BULO - Breathing Training Device + Guided Breathing Exercise Mobile App: Optimize Your Training with a Smart Personal Trainer for Better Breath Control by Rudy Santos

I thought long and hard about what to say about this product. As a swimmer and runner who always wants to improve, I was hoping this device could do something good. It's hard to say if he is or not. Basically you get a handset with an airflow sensor that interacts with the phone app. The app uses a sensor to calculate your breathing rate and volume, and based on that, gives you an estimate of your exertion and "age". To improve your lung function, he uses the same mechanism to guide you through a series of breathing exercises. He first told me that I have the lungs of a 98 year old despite being an average swimmer and runner and an above average cyclist. However, based on that estimate, I was able to improve my score by about 8 years in just a few weeks with the included exercises. On the road and in the water I didn't see any real difference in my performance. I suspect it may take more than a few weeks. However, it has helped me think more and focus on my breathing, which is helpful in itself. So is it really valuable? I honestly can't say. If you like athletics gadgets like me and are willing to try something to see if it helps, I say buy it. If you're looking for something that's guaranteed to result in better performance, that's what I say next.
