Fitness Exercise Trainer Portable Adjustable Trainer for Oral and Muscular Exercise - for Daily Fitness Training, Easy to Clean Adjustable Exercise Trainer for Fitness Training（ White）

I added this to my cardio routine, but it was tougher than I thought it would be. Possibly could have helped me better in my younger days as an actual athlete.

tested the Fitness Exercise Trainer, designed for oral and muscular exercises. Initially, I didn’t feel like it was working, but after a few minutes, I definitely noticed its effects.This portable and adjustable trainer is aimed at daily fitness training and is easy to clean. Despite a slow start, it proved effective over a short period of use.Overall, if you're patient and give it a chance to show its effectiveness, this exercise trainer can be a unique addition to your fitness regimen.

This trainer is great for increasing my lung capacity. Adds diffidulty to my exercise.

Very basic product. I'm sure it works as intended but it was very cheaply made and not worth the purchase.

Tools like this can be helpful for preparing for a trip at altitude or for exercise. I found that this was a bit too restrictive when starting out, and there wasn't much adjustment when you were beginning. The device seems to work well overall, but I would say it is for advanced breathing training only.

I have been interested in breath trainers for some time, and I thought this item would be a good entry into the world of breath trainers.The first two times I used it, I saw the potential that breath trainers have. I adjusted the knob to get the full benefit of the trainer. I was, at first, well pleased.BUT the third time I used it, the knob had lost its ability to tighten, and I was simply breathing through a piece of plastic with no resistance training on the exhale.This was not well made and not worth the price they're charging.

I like to keep my lungs healthy for exercising and since I have a family history of COPD, I feel like this trainer will help with lung capacity. It's easy to use, and even when it is adjusted to the highest setting, it feels kinda like you are blowing up a balloon. It also reminds me of the spirometry machines that they give you in the hospital after surgeries or procedures to help with your breathing.

This is a relatively simple product, and it's easy to use, all things considered. The mouthpiece has a bit of a plastic taste upon initial use, though the mouthpiece itself is not a major component. There's two dials at the end of the tube, and turning them separately required some force at first. The top one is the only one that you're really supposed to need to adjust. The amount of adjustment is relatively minor, not necessarily giving a very large range of breathing restriction (or lack thereof). It's primarily focused on heavier restriction of air, so if you're starting out, it may be too much. The overall product feels relatively cheap, though it's simple enough that this is not necessarily a problem.
