The other day I was searching YouTube and came across some rather extreme ab workout videos that I thought would be good to share here on flatstomachblog.com.

They are rather advanced workouts and I would recommend trying them out with caution, especially if you are a beginner or have any health concerns.

I hope I can build up to completing the “Wicked Wiper” soon enough.
