TRAININGMASK Training Mask - Workout Training Mask 3.0 Breathable Cardio Training Mask for Running, Cycling, and Exercise, Black Mask

If you are one of those who holds their breath during heavy lifting. Try it on but less resistance it will put you in rhythm of breathing. And hey pull all the faces you want and all the noise you want to make without disturbing any one around

Excellent product for increasing the intensity of your workout. Start off gently and build up your tolerance slowly. Good adjustment options. Item fits as per the size guide for me.

Excellent piece of equipment, but needs to be wrap up more when being shipped out received it with plenty of damage to the box.

Product does the job I believe. Only downfall it's alot of money and didn't mind paying it as I was lead to believe it came with a storage case/box which now I see I'm not the only one who did not receive it ,in that case we should not be paying that price. Great product very poor advertising

excellent👍

the complete product did not come there was no box to store the mask as shown in the picture. Overall, I rate the quality at 2. 50 f not worth spending

Un outil dentrainement spécifique au top. A ne pas confier a des sportifs debutants. Pour les athlètes cherchant des training Huit très hardcore. C'est ce qu'il vous faut.

Ottima qualità e comodissima da indossare. Il pacco é arrivato nei tempi previsti e completamente integro. La uso da ormai due settimane senza aver riscontrato problemi con velcro e cuciture. Mi raccomando rispettate le taglie per il massimo comfort.

Cumple para lo que fue hecho el producto, tiene diferentes niveles para respirar, de ésta manera, fortalece tus vías respiratorias, al "batallar", para respirar, por decirlo de alguna manera, hace que aumente el CO2, y ésto favorece un mejor aprovechamiento del oxígeno, ya que se libera en mayor cantidad para usarse en el cuerpo, ¡100% recomendado!, éste producto lo vi en un libro que se llama, La respiración curativa, por eso lo compré
