Testoboost Pro One fitness trick to keep in mind is to push your tongue upward into the top of your mouth while you are doing sit-ups or other floor exercises. With your tongue pressed into the roof of your mouth, it will engage your neck's muscles and keeps them aligned while you are exercising your abs. You can avoid harmful strains or injuries this way.
