Seated Dumbbell Crunch:
FOR YOUR MID SECTION THE CLASSIC CRUNCH.
2-Raise your upper body until your shoulder blades no longer touch the bench completing a full crunch. Every repetition you should feel a contraction.
3-It is exceptionally important when doing a seated crunch to squeeze and hold for one second. After you crunch go back down repeat for 15-25 repetitions for each set. Crunching is exactly that!
