Instructions
Ab Roller
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.
Oblique Crunches
Lie flat on the floor with your lower back pressed to the ground. For this exercise, you will need to put one hand beside your head and the other to the side against the floor.
Make sure your feet are elevated and resting on a flat surface.
Now lift the shoulder in which your hand is touching your head.
Simply elevate your shoulder and body upward until you touch your knee. For example, if you have your right hand besides your head, then you want to elevate your body upwards until your right elbow touches your left knee. The same variation can be applied doing the inverse and using your left elbow to touch your right knee.
After your knee touches your elbow, lower your body until you have reached the starting position.
Remember to breathe in during the eccentric (lowering) part of the exercise and to breathe out during the concentric (upward) part of the exercise.
Continue alternating in this manner until all of the recommended repetitions for each side have been completed.
Verdict
Both exercises target the abdominals. Ab Roller is a intermediate exercise using other, while Oblique Crunches is beginner and uses bodyweight. Choose Oblique Crunches if you're looking for a more accessible option, or Ab Roller for a greater challenge. Ab Roller is a compound movement working multiple joints, making it better for overall strength. Oblique Crunches isolates the target muscle for focused development.
