This is part 2 of my weekend ab series. As I begin to wrap up my 30 days of motivation, I wanted to make sure I leave you with some good training tips. Be sure to subscribe to get all of them!

If you can’t commit to going to the gym every day, commit to working your abs every day – even if it’s just one or two exercises when you can. Anything you will do will be better than nothing. And, doing abs every day helps you stay focused and helps you stay in a routine. Plus, a strong core is SO good for you!! It protects your back and prevents injury.

Not all ab exercises are created equal though – and, there are more ab exercises than just crunches and sit ups. Here are 40 ab exercises, complete with links to video instruction. Just click on the exercise to bring up the video.

Post your favorite ab exercises in the comments below!! I’d love to hear about your favs too!

20 Exercises for Tight & Flat Abs

While many of the exercises may work one part of the abs more than the other, the main benefit is the tightening affect it has to flatten the abs and and trim the waist. These are model-makers right here! (Of course you should read my last post about what really makes abs, but these are great to add to your ab tool box).

TRAINER TIP: If you want a flat stomach make SURE you are holding your tummy in tight while doing these exercises. Taking in too much air or not really engaging the abs correctly can prevent you from getting all that you want out of these exercises.

10 Exercises for a 6-Pack

These exercises help build those ice-cube abs you see on people like Gwen Stefani and Ryan Reynolds. Of course, some of your ability to get a six-pack will depend on genetics. Some people have compact ice-cube like abs, while others have a larger flat abs (this can be due to a longer torso). Some people only show four or six cubes, while others seem to have an eight-pack. That’s just how God made them. However, you can definitely develop your abs more and make the most of what you have. Here are the go-to exercises for building more definition.

10 Exercises for Obliques & Serratus

Not everyone cares about obliques and serratus (the muscles along your side). You may not even see them until you start getting really lean, but you should still work them. The number one reason to train them is because they bring the waistline in, acting like a girdle.

Be careful though. Doing weighted side-bending exercises can add width. Do you see that big chunk of meat on the girl in the picture (below) right above her hip? That’s her very developed oblique. Big obliques can add width, and if you have any fat on you, it could pose as a love handle. Of course she’s lean and looks great, but that’s just a small word of caution. If you want to keep that waistline small, all these exercises are great, just avoid weighted side bends. Give some of the exercises a try!
