I like simple…
And when it comes to working your abs, there’s no need for a million different exercises.
Instead, I like to group a few together and hit rinse and repeat.
For example, here’s a 4-minute routine you can do once, twice or even three times if you can manage it.
Give it a whirl and let me know how it goes :)
P.S. Don’t forget to like and share with all your friends ;-)
