Not really an ab workout, but a decent bodyweight workout. Some of those are tough exercises....
Np. I registered to the guy's site for free, he's got a lot of cool videos and articles.
- I'm not affiliated with him in any way in case you're wondering lol.
I like the format of the site though and the programs are very easy to follow.
may not be an ab workout but its a workout that will get you abs.
