3 PCS Portable Breathing Trainer with Adjustable Resistance Settings (Black/Grey/White)

My son had eard and think it’s help with breathing problems

These are a great exercise tool for those looking to increase lung capacity and core strength. Great purchase!

Very convenient to work out in!

Brought this to use on our cruise and Hikes. The adjustable straps works well. It can fit both me and my husband and just an image I am 5’2 and he is 6’6

This portable muscle trainer is okay for light resistance training, but if you’re looking for something with strong tension for serious strength building, this might not be the best option. The adjustable resistance is nice, but even at the highest setting, it’s not as challenging as I expected.It’s lightweight and easy to clean, which makes it great for travel or quick workouts, but over time, it doesn’t feel as durable as I’d like. Good for beginners or light endurance training, but not ideal if you need higher resistance for real muscle gains.

Ease of use , functionality was simple !

I exhale and no air comes out no matter where I twist it.

User it for vocal training and was able to increase my breath time to 40 sec in 2 weeks at the hard level
