Ab Roller vs Oblique Crunches - On The Floor

Hold the Ab Roller with both hands and kneel on the floor.

Now place the ab roller on the floor in front of you so that you are on all your hands and knees (as in a kneeling push up position). This will be your starting position.

Slowly roll the ab roller straight forward, stretching your body into a straight position. Tip: Go down as far as you can without touching the floor with your body. Breathe in during this portion of the movement.

After a pause at the stretched position, start pulling yourself back to the starting position as you breathe out. Tip: Go slowly and keep your abs tight at all times.

Start out by lying on your right side with your legs lying on top of each other. Make sure your knees are bent a little bit.

Place your left hand behind your head.

Once you are in this set position, begin by moving your left elbow up as you would perform a normal crunch except this time the main emphasis is on your obliques.

Crunch as high as you can, hold the contraction for a second and then slowly drop back down into the starting position.

Remember to breathe in during the eccentric (lowering) part of the exercise and to breathe out during the concentric (elevation) part of the exercise.
