Abs and planks

You should get an idea of how much is too much from how you feel.

You shouldn't need to do it every day and I doubt it'll help much if you're after muscle growth.

If you're after muscle growth, you need something where you can increase resistance.

With the ab roller, once you can do it on your knees, move to doing it from standing and go a little further each time.

The routine I like is (3x12 for all):
Decline weighted sit ups.
Weighted hanging leg raise
Dumbbell side bends
Ab roller.

Make sure you're getting enough protein.

Hello, I am new to my fitness pal.
I m wondering if I do planks every day and the ab rotater machine every other day if it will be too much work on my ab muscles. I am 20 years old and male. Would doing that exercise hinder muscle growth?

You mention muscle growth - are you eating a calorie surplus? You won't get any muscle growth if you are eating at a deficit.

If you are eating at deficit, then your abs will become more defined owing to fat loss, not planks.
