Let’s get one thing straight; ripped muscles will never trump a broken set of gnashers. That said, a clenched jaw may well assist with those all-important lifts down the gym, according to new research.
A study carried out at the Ramon Llull University in Spain found that gritting your teeth mid-exercise can result in a strength boost, particularly during resistance training.
Participants in the experiment completed a 30-second maximal effort workout with a resistant equivalent to 7.5 per cent of their body mass.
Guys who bit down throughout were found to produce up to 12 per cent more force for lifts, and rowing drills also saw improvements, with the clenchers quicker to perform the workout.
So next time you hit the squat rack, don’t forget to pack a fitted mouthguard. Then simply bite down, and feel the burn.
