Okay, I get it. Everyone starts somewhere. I commend you for wanting to do good for your body and start working out! However, these ten-minute ab workouts are meant for convenience as opposed to a fitness routine. If you do the same exercise every day for a month, your body will eventually grow accustomed to it and you will plateau without making any more progress. I promise you, after these thirty days, you are going to be discouraged without any further change.
Though it's a fun challenge, I recommend diversifying your ab routine in order to see optimal results. Your abdominal muscles are actually very complex, comprised of many different parts. If you diversify your workouts, you'll ensure that every muscle is being used in different ways each day. Your body will continue to be shocked, therefore building your core and as a result, you will see results! If you are working the same muscle every day, your soreness is going to deplete and you will not see results, at all.
I think people are miseducated on the basis of how abs are formed and how they progress. Not many believe me when I say 80% of it comes from the kitchen! Most people actually have the core strength that it takes to HAVE abs. However, the majority of those people do not realize that abs are ultimately created through Most people I know don't even train abs on a day to day basis, yet still have the SICKEST abs I've ever seen. (Just a fun fact: Most of the boys with abs who I know personally said they do leg lifts once in a while, and that's it). Things like lifting, yoga, and kickboxing can increase your core strength by a TON.
In my opinion, adding weights to my ab workouts make it so much better! I like keeping my rep range lower and adding a 10-pound plate to my ab workouts because it actually gets me sore, and that's what we're aiming for. Sometimes it's cool to be sore to the point where you can't laugh, and these ten-minute ab workouts just aren't going to accomplish that.
I think the BIGGEST problem with these 10-minute ab routines that are done every day is the fact that you're doing them, every. single. day. I've come to the conclusion that newbies think it is okay to train abs every day, and while that may be your mindset right now, that's probably only optimal for those who have trained abs for years. Like I said earlier, you engage your abs in different compound movements during lifting, such as squats and deadlifts. So I can promise you, your abs are still going to get stronger. It's almost silly to focus on the same workout every day.
Another problem encountered from getting into this routine is that - it's not much a routine at all. You will get bored from doing the same thing every day, which will easily be unmotivating. I speak from experience when I say this because I used to have a notes section in high school that comprised only of these ten-minute workouts. I'd do the same one every day and get super unmotivated because it just wasn't entertaining anymore. You need to stimulate your brain so it stays interested.
All in all, I still get it. I get why that 10-minute ab workout looks appealing at first. And it will be! Just remember it's important to change it up and you have to work hard in the kitchen. Putting whole foods and taking care of your body is the only "secret" that ensures results.
