A Sleek Ninja Sneak Preview!

Posted by Sarah Lobban on 3/14/2019 7:00:00 AM


“Exercise, diet and sleep,” Eric the Trainer says. “This is the science of transformation.”

The creator of the Sleek Ninja fitness program speaks from experience – before this celebrity trainer created his program or took on a single star client, his was the first body he transformed. Eric Fleishman was a self-described “weakling.” He began training in martial arts and fitness as a young teen, and discovered his calling.

Today, Fleishman, better known as Eric the Trainer, is clearly nothing of the sort. He’s one of those guys who looks like he could effortlessly curl my bodyweight. But you can tell from the way he moves – fluid, almost catlike – that his is a functional fitness. No “bulk for bulk’s sake” here!

You may have watched Eric's training skills on the TV show Celebrity Sweat, alongside Hollywood stars, major-league athletes, and rockstars. Now it's your turn! Eric the Trainer is bringing Sleek Ninja to the 2019 Martial Arts SuperShow, coming this July to Las Vegas, so if you’re attending, you’ll have the chance to try this workout for yourself in one of our early morning workout sessions! (You’ll also be able to take his Instructor Training seminar to learn how to boost your school’s health.)

Want a sneak peak at Sleek Ninja? A few weeks ago, Eric the Trainer made an in-person appearance at Century HQ, and lead an hour-long Sleek Ninja class for employees! I jumped at the chance to take it, because who doesn’t want to be sleek? Let alone a ninja!? Here’s how it went!


(Quick note: Sleek Ninja, of course, has more material than what we were able to do in one hour. I did not do every Sleek Ninja routine. I would not be able to move to type this.)

We warmed up with some stretches and yoga-type moves. This is the calm before the storm; the gentle intro that tricks you into thinking the rest of the workout will be easy. The warmup lies.



The first exercises were a variant of the leg kickback: on all fours, lift one leg towards the ceiling, pointing your toe up. You the pulse that leg upwards, keeping it as straight as possible. We did multiple sets of left and right, with a final alternating left-right-left set at the end.

We ran through several similar exercises, including a sort of side-crunch kick that had us drawing our knees towards our shoulders.

However much you think this hurt, it was actually worse. In a good way. 


“If you want to change it, you have to move it,” Eric explained. “So if you want a more toned waist, you have to do exercises that make it move.”

This is one of his workout plan’s underpinning philosophies. If the pain it my sides the day after was any indication, it works.

We cycled through another set of kicks, and another. At one point, my friend and coworker Danielle, who had also come to the on-site class, looked over at me and mouthed, “I’m dying.” I would have responded but I was also too busy dying.

Thankfully, after the kicks and several sets of lunges up and down the length of the gym, we paused for a few moments to stretch. Then it was on to upper body.

One of the cool things about Sleek Ninja is how refined and specific Eric has made it. When we did pushups, he listed several variants aimed for developing different parts of the chest, as well as variants for men (broader chest) and women (toned without broadening). Of course, these exercises will work for either gender – they’re just based on common goals. (Most women I know don’t want pectorals that look like they could crack a walnut.)



Finally, we got to the cool down, which is great because GOSH DARN IT I was starting to feel not only the Sleek Ninja training but the legs workout I’d done the previous day. There were more stretches, and I definitely did not go back to my desk and nearly fall asleep.

Okay maybe I did.

Don’t judge.

If you’re looking at the pictures from this workout, thinking, “Well, these just look like normal exercises” – don’t be fooled!

Yes, they’re “normal” as in, you don’t need a Ph. D to figure out the movements, or complicated machines. But Eric has added little tweaks and touches to each exercise to make them more effective and/or better tailored to your specific body goals.

Also, Eric is just a truly, genuinely nice guy. Like I said, the could stack and bench press any two people from the class at Century, but there’s not a shred of vanity in him. His enjoyment of fitness, both as an interest and in himself, personally, is comparable to the enjoyment and appreciation a high-level master would have for martial arts. (This attitude of humility may, in part, be due to the fact that Eric himself is a martial artist with a black belt in several styles).

There are plenty of ways adding Sleek Ninja to your school can help. If you have students who compete, they’ll jump at the chance to get help losing a little extra weight. Those parents who you only see as they drop their kids off? Get them through your doors and training as well! Sleek Ninja can even help your instructors and black belt students look more the part of high-level martial artists. As Eric says, “If you see a five guys walking around, you should be able to tell by looking which one the martial artist is.”

And I know how time in Vegas adds up – between the buffets and the endless bars (why are there so many bars?), your body will probably appreciate some time spent engaging in healthy exercise. And after you’ve spent an hour or so working on your Sleek Ninja physique, you may well decide that this would be a great fit for your school. Either way, you have a great workout to gain and nothing (except, like me, some extra padding around your gut) to lose!
