You upgrade the training in every way you can! So I went from the #trainingmask2 to the #trainingmask3 and I must say it's much more practically! Like all of us Instagram scrollers... with the new mask you just scroll to create the resistance! Keeping my cardio on point! #cardioking #elevationmask #trainingmask #badass
