The decline crunch exercise allows you to keep your legs steady and isolate all of the ab muscles.

Steps :

1.) Start off lying with your back flat on a decline bench and placing your feet securely under the foot rest pads as this will be your starting position.

2.) Then place your hands either across your chest or on either side of your head then lie back fully and slowly rise with your upper body, crunch your abdominals.

3.) Continue forward until you feel a tightening in your ab muscles and hold for a count.

4.) Return back to the starting position and repeat for as many reps and sets as desired.

Tips :

1.) Use the full range of movement in this exercise for the optimal results.
