Please consult a physician before starting this or any exercise program. Oblique Crunch Do three to five sets of 15 to 20 reps on each side. Lower Ab Crunch Do two to three sets of 20 to 40 reps. Both genders should do these exercises two to four times per week. Men respond better to less reps and more sets.
Women respond better to a higher repetition and fewer sets.
Switch the two, and women end up getting bigger, usually a bad thing, and men end up with a lack of tone. Each of these exercises is for the waistline, but each has its own target. Men should concentrate on the sides or obliques, while women should focus on the lower tummy or lower abdominal. Both sexes should exhale on the up motion and use slow and controlled movements. Unweighted Lunge Do one to two sets of 10 to 30 reps.
