Pick an activity; better yet, choose three. What muscles do they have in common? Let’s say you went with “jogging”, “jumping jacks” and “playing chess” – that last one should mess up the results, right?

Nope.

Every move you make from the moment you get out of bed - actually, even the act of climbing out of the sack - uses your core to bend, twist, walk and stand and even sit erect. The muscles of your lower torso make it possible for you to stand upright, shift your bodyweight and move in any direction. Remember the “playing chess” example above? You use your core to maintain your posture in the chair and as the base to lift your arm to move the pieces. Needless to say, a healthy and strong core is extremely important to your ability to perform any action.

So, how do you strengthen the muscles of your abdomen and lower back to develop a strong core? It starts with one of the easiest exercises to perform – the Sit-Up.

Since almost every move you make uses elements of your core, there are literally hundreds of exercises that can be used to strengthen and tone your abs and lower back. I’ve taken the easiest to master and most effective exercise – the Sit-Up - and created a program that will challenge you to build up to 100, 200, even 300 reps while learning and performing over 30 other exercises to develop total core strength and improve your posture and athletic ability in the process.

“Wait, I’m confused – you must be talking about crunches. I’ve been told that sit-ups are bad for your back and we should do crunches instead, right?”

Sit-ups have gotten a bad rap over the last decade or so, and while it’s true that performing sit-ups (as well as dozens of other exercises) with bad form has the potential to strain your back this book is dedicated to rebuilding the proud legacy of the sit-up as one of the most beneficial exercises for developing your core and putting to rest misconceptions about the danger of sit-ups by teaching proper form.

“Ok smarty-pants, how are you going to accomplish all that and make sit-ups en vogue again?”

Simple: I’ll start by dispelling myths about the dangers of sit-ups and explaining proper form - which just happens to be the same form that’s used in basic training PFT by the military - to lessen the stress on your hips and back, provide multiple different variations of the sit-up move for beginners through experts and demonstrate 30+ additional exercises designed to strengthen your abs, back and hips to enable you to do 100, 200 or even 300 Sit-ups!

In as little as 15 minutes a day, 3 days a week, by following the program in this book you can improve your posture, boost your strength and athletic performance, lose weight and burn fat to develop the body you’ve always wanted!

It all starts with a simple sit-up move – pretty easy, right?
