Hanging Leg raises enough for stomach routine?

[MACKATTACK]

Are hanging leg raises enough for a stomach routine on certain days.

Then maybe regular crunches, side crunches and crunches on exercise ball with holding at top on another day. I do abs 6 days a week.

This is what i do because of my two herniated discs. For me, it relieves unnecessary strain on my lower back and yet still allows for a decent ab workout, imho.

You could just do hanging leg raises if you choose. I would do the bicycle. The American Council on Exercise found out just which exercises target the abs in the most effective way in an ACE-commissioned study.
1) The Bicycle

2) Leg Raise: The key to keeping this move safe and effective is, first, to avoid swinging the legs or using momentum to bring the legs up. Second, keeping the knees bent will help you focus more on the abdominals and less on the hip flexors.

3) Exercise ball sit ups: On the ball, the abs do more work, but you still involve the entire body to help stabilize you throughout the movement, a nice bonus that floor crunches don't always offer.

4) Vertical Leg Crunch: It's similar to a regular crunch, but your legs are straight up, forcing you to use your abs to do all the work and adding intensity to the exercise.

5) Long Arm Crunch: Changing the traditional floor crunch by straightening the arms behind you. This adds a longer lever to the move, adding a bit more challenge and difficulty. Emphasizes the upper part of the abs.

6) Reverse Crunch: With this move, you're curling the hips off the floor, so you'll feel this in the lower part of the abs. The key to this move is to avoid swinging the legs to raise the hips. This is a small, subtle move, so you only need to lift your hips a few inches off the floor.

7) The Crunch With Heel Push: looks like a traditional crunch, but in this version you push your heels into the floor, which engages the abdominals more than regular crunches.

If your doing abs 6 days a week then yea for sure its enough as long as you are performing them correctly and feeling the muscle contraction
