GO2 Endurance Workout Device for Improved Breathing and Increased Oxygen Flow While Running, Biking/Cycling, Exercising, Hiking and High Altitudes Made in The USA, Blue

My brain and my cardiopulmonary system are not very good at working together, and as a result I struggled frequently to keep my breathing in check and my HR low. Enter the Go2 device. I’m not sure about the VO2Max increase, because I don’t have a lab, but I do know after one week of training with this I ran a marathon PR and never struggled with my breathing rhythm, or felt short of breath. This is a fantastic little device for anyone who’s trying to improve their performance.

Excellent product, used this for 2 weeks now and run about 20 miles in 2 weeks...breathing and heart rate have gotten better to were I don’t feel tired after my runs. My first 3 runs I’ve had to pull the mouth piece out to spit a couple of times; but everything other than that it working.

The device works well for what it does, but after a while the effectiveness seems to lessen. I wish it came with an ability to put in new attachments to create more resistance, but I still use it and I get good training out of it. Not a bad purchase if you aren’t training super hard. I would definitely recommend it for beginners

When I was younger I considered myself a runner who rarely dealt with asthma-like hurdles---easily marathon bound. Since then, I became an asthma "sufferer" who takes 2 inhalers twice daily, 2 pills twice daily (to survive) and uses an emergency inhaler for immediate lung support as needed (which was daily). Definitely no marathons happening with these lungs!One day my sis gifted me with my GO2. It changed everything. I could breathe effortlessly, take walks--even run without using my emergency inhaler or fear of suffocation. Most importantly, my lungs feel stronger even when I'm not using this miracle device AND continue to get stronger the more I use it. I no longer worry my lungs will fail me....So on December 8, 2019, I attempted and finished my first marathon. MY GO2 MADE ME A MARATHONER! I still have asthma but no longer "suffer" from it.

The packaging doesn't come with much and outside of watching videos and reading the small paper that came with it I had no idea how to get started using the GO2. However, I learned this is one of those products that you have to use more and learn how it's supposed to work. I wouldn't recommend this to a newer runner, but someone who does cardio somewhat regularly. Cut a minute off of my mile time and still improving. I'm rating low due to the learning curve associate with initial use.

Hola, mi Go2 llegó desarmado como se ve en la foto, he tratado de ajustarlo pero es imposible. Las ranuras son minusculas y es sitema parece imposible de manipular para un ser humano corriente. Que deberia hacer?

It helps me with my breathing when I run and yes I did droll a bit at first, now when I feel I might possibly start to droll I take it out give it a shake and pop it back in. It certainly has taken off 6 mins off my 5K & 10K runs.I've used it when biking and don't take it out for fear of it dropping out of my had and not being able to find it.I did find the first couple to times I used it the sides of my mouth was a little sore, but not so much now. It's a game changer and I would say it's worth the money

Have been using this with a variety of different workouts as I do triathlon training. Have used on indoor biking sessions, runs (short and long), and body weight exercise circuits.From first breath, you become immediately (hyper) aware of breathing patterns, rate, and force. Starts adjusting your mindset to focus on the breathing and let the rest of the workout to take care of itself. Only takes a few workouts to begin getting more and more comfortable using device. I will say, saliva output has definitely increased, but learning to control that more and more as usage increases. Tracking similar routes, efforts, etc. to see physiological changes for long-term benefit. Excited to see progress as the journey continues.

This is a piece of plastic. I am a cyclist and this is sooo impractical and limits air intake and air blow out. To me a piece of garbage

Si Funciona, lo recomiendo, tarda uno en adaptarse inclusive me provocaba náuseas, pero una vez que te adaptas es una maravilla, alcanzó un pace más rápido y mi frecuencia cardiaca no se eleva tanto!!!!

AVOID!I bought this after seeing endless adverts in my instagram ads. It arrived and I was disappointed with the whole item. The build quality is terrible for almost £60. Just a thin piece of moulded rubber with a rubber band holding it together. I tried using it while running and got zero benefit from it.

Buena compra

no me parece que funcione , pues es muy ligera la resistencia
