I’ve already talked about why it’s so important to train the abs and how to do it properly while avoiding the most common mistakes. There are numerous fantastic core exercises, but this one is extra fun.

As long as you’re able to main the right position, challenge your friends and give this a try.

Just make sure you can already do ab roll outs with good form, otherwise this ab challenge will turn into a train wreck!

So, here you go! See how fast you can row 100m with your abs! Challenge your friends.
