How long to workout to have good visible abs ?

How long should I workout to have good visible abs ? How long does it take to make a significant improvement ?

It depends on how big your abs are and how much body fat do you have.

If you have low body fat and you focus only on your abs, it can take 6-8 weeks to get visible improvement.

If you have low body fat and you do full-body training, it can take 3 months to visibly improve your abs.

If you have average body fat, it can take 3-6 months to have visible abs.

If you have higher body fat, it can take 6-12 months or even more.
