But if your main goal is adding muscle definition to your midsection the best way to get abs is via weighted ab workouts.
The first useful method is that Squat To Overhead Press With Rotation. How to: Start standing, feet hip-distance apart, toes pointed out slightly. Dumbbells should be in either hand and resting lightly on shoulders. Sit back into a squat until thighs are parallel with the ground. Drive up through heels to standing while raising right arm toward ceiling, turning torso toward the left, and lifting right heel to pivot on it. Come back to center as you sit into the squat, then stand while raising left warm toward ceiling, turning torso toward the right, and lifting left heel to pivot on it. That's one rep.
What's more, the second one is that Leg Drops. How to: Lie on your back with a dumbbell held in between your hands and extend your arms. (Think wrists over chest NOT your face.) Lift your legs up directly over your hips. Lower your left leg down as low as you can go without your lower back arching up off the mat. Return to start, and repeat on the other side. That's one rep.
Finally, the last one,Renegade Row. How to: Start in plank position, holding dumbbells in either hand on the ground. Pull right elbow toward the ceiling until right wrist is near ribs, then lower it down. Repeat on opposite side. That's one rep.
These methods of building muscles have an essential equipment, that is, dumbbells. This product is very suitable for ladies. I think that is worth to purchase.
