I’m a nut about my abs. I won’t even lie! I love the feeling I have after a nice ab workout – I sit a little higher in my seat, I feel a little more secure in my movements, and I go a little harder in my other exercises, because I know that my midsection is stronger.
Having said that, this exercise here kicks my butt.
How many should you do? Honestly, I can’t say. I started out with 3 sets of ten. I’d do ten (5 on each side,) then breathe for ten seconds… ten more, take a breather… then ten more.
Give it a shot, and let me know how it works out for you!
