Son asked for it

My son asked it to have this. He’s in football, wrestling, and track. Restriction on breathing as advised to help with winding during jogs around the block. He uses it most nights and no complaints about the functionality “it’s adjustable “.

Frequently asked questions

How does it work?

The U-Pro operates on the principle of resistance training for your respiratory system. By adding resistance to both your inhales and exhales, it forces your breathing muscles to work harder, making them stronger and more efficient over time. This improves lung capacity, oxygen efficiency, and overall respiratory endurance.

Do I need to be an athlete to use this?

Not at all! While athletes see significant performance benefits, the U-Pro is beneficial for anyone. Whether you're climbing stairs, playing with your kids, or just want to breathe easier in daily life, stronger breathing muscles help.

How long do I need to use it each day?

Just 5-10 minutes per day is sufficient for most users. Consistency is more important than duration. Many users incorporate it into their morning routine or pre-workout warm-up.

What specific benefits will I experience?

Users typically report:

  • Reduced breathlessness during intense exercise
  • Improved endurance and stamina
  • Faster recovery between intervals or sets
  • Better oxygen efficiency during workouts
  • Increased lung capacity and VO2 max
  • Enhanced breath control and pacing
  • Less fatigue during daily activities
  • Improved performance without extra training volume
Will this help me run faster?

Yes! Respiratory muscle training has been shown to improve endurance performance by 3-5%. For runners, this translates to better race times, the ability to maintain pace longer, and reduced breathlessness during hard efforts. Your breathing muscles won't steal oxygen from your legs when they're properly trained.

Will it help with my VO2 max?

Yes! Regular use of respiratory training devices can improve VO2 max (your body's ability to use oxygen during exercise). The advantage is you can improve VO2 max without the joint impact of additional cardio training—perfect for recovery weeks or when dealing with injury.

Is the U-Pro safe to use?

Yes, when used as directed. The U-Pro is designed for safe respiratory muscle training. However, start with low resistance and progress gradually to avoid overworking your breathing muscles.

Can I use the Respiratory Drops with the U-Pro?

Absolutely! In fact, we recommend it. Add a few drops of the Respiratory Drops into your U-Pro before training sessions. The cooling botanicals (peppermint and menthol) enhance the experience while you strengthen your breathing muscles.
