When it comes to ab training, too many people get caught up in just going through the motions and thinking that because they trained their abs that it’s “good enough”.
When really, if you’re going to spend the time to do abs, you might as well get a reward from it!
The first mistake I see is not creating the mind/muscle connection with your abs. People get down on their ab mat and get from point A to point B and as long as they got 10 reps, they’re happy. When truth is, they aren’t actually focusing on contracting their abs AT ALL. Make sure the next time you go to do an ab exercise, you’re specifically targeting the ab muscles that you’re supposed to be hitting.
Next, people don’t give a shit about their breathing. And most of the time, it isn’t their fault, they don’t know any better and just let their inhalation and exhalation flow naturally. But if you were to take control of your breathing, your ab contractions would be taken to the next level. The next time you go to do abs, make sure you exhale completely before you crunch and inhale on your way back down. I guarantee you feel a better contraction.
Last but not least is momentum and one that I see a lot. Too often, I see people using their arms to get themselves half way up the crunch or their legs to cheat the bottom half of a reverse crunch, etc.
