Review on Enhanced Performance Mouthpiece by New Age - Advanced 5DS Technology for Sports and Fitness - Focus on Lower Jaw and Zero Contact by Sean Carter

They won't make you incredibly strong just by putting them in your mouth. I train twice a day for amateur bodybuilding competitions, I also tend to clench my teeth or bite my tongue when I lift weights. I thought it would be an easy win. They're great for biting and for extra strength on the last few reps. But if you bench press 275, you're not going to get to 315 the next day. If you can get 275 pounds in 5-8 reps, it will help you stay in shape for those last few reps and lift the 8-rep weight more consistently. All in all I would recommend them, I have a moderate gag reflex and they can cause it at times considering how big they are but that's just me. Will buy again when my current pair wear out. One star deduction for extravagant statements
