Man vs. Machine: How Best to Lose Unwanted Fat
So here it is: Machines do not work – they actually work against you.
I've spent over a decade working and consulting for fitness companies and I can tell you as an "insider" that machine circuits are the favorite selling tool to convince beginners to sign-up. They lead you to believe that they are easy to use and will get you results.
First off, most of the time you do not even know which way to get into one of those massive contraptions and second, they are at least 30% less effective than other forms of exercises.
Closed chain (feet on ground), compound exercises (multi-joint) are head and shoulders better than machine workouts. There's no comparison since machines do not allow you to move how your body was designed to. The great thing about these recommended non-machine workouts is that you can take them anywhere with minimal equipment. I usually just choose a dumbbell based workout or even body weight only exercises.
What about ab machines?
Do not even get me started on ab machines and the infomercials that promote them! Without going into it too much detail, you'd need to do about 25,000 crunches to equal 1lb of weight loss and you'll still never see your abs. To really see your abs you need to shed the fat that is covering them (not make them stronger, but they do not tell you that …).
The fitness models you see on TV have probably never used or heard of those products before being paid to promote them.
So, not only are they ineffective, but most ab machines put you at a high risk for injuring your lower back from too much forward bending without counter-balancing it with any back extension … and nobody with a bad back has good looking abs .
You already have everything you need to get your body in great shape. Skip the fancy equipment and stick with what works. Your body will look and feel healthier and be in better shape!
