I had no idea how much harder I could strain until I started training with a New Age Mouthpiece.
Squatting, deadlifting and benching with the 6 DS Heavy Lifting is whole new experience in effort!
I have 4 different mouthpieces plus back ups just in case.
I have a mouthpiece for accessory lifts, a different one for mountain biking, plus another for pad drills and heavy bag training.
