Space Is Limited To Ensure Maximum Results

*** Here’s How To Get Started ***

1) We only work with hard working athletes and supportive parents.

2) If you’re looking for the gym close to home or cheaper than everyone else, we are NOT the place for you. We focus on Excellence, not convenience or discount prices.

3) We specialize in training athletes and have been leaders in transforming the lives of athletes since 2002. We are not like “everyone else” out there training athletes.

4) Do Not sign your child up for a trial workout if you are “too busy right now” or “we need to think about it”. To succeed you need a sense of urgency. Procrastination and excuses do not contribute towards greater success.

Thank you so much for all that you’ve done for me! You’ve taken me from a participant to a meaningful contributor.

When I came in to the underground I was long jumping 15 feet and now I’m leaving jumping 17.5 feet.

I’m also leaving with 2 school records and many county / division honors.

You’ve always supported and motivated me to break records. Thank You!

YOUR Child’s Success Is Our #1 Priority.


Dear Supportive Parent,

If you’re here, reading this web site, it’s quite likely you are searching for the best resource to help your child reach his / her potential in sports. You’re looking for Coaches who are true experts in the field of athletic performance, Coaches with a long track record of success as well as Coaches who genuinely care.

As a parent myself, I understand how important this is for you and your child. Our commitment to your child is something we take very seriously, which is why we are constantly improving our training methods to ensure that your child gets nothing less than the best training in NJ.

You’ve probably seen other Strength Coaches trying to copy our web site and copy how we train, yet they simply can’t deliver the type of results we Guarantee and we never fail to achieve rapid results with each and every athlete who walks through these doors.

We Guarantee results or your money back, no questions asked.

At The Underground Strength Gym, you will NOT find a pretty gym with fancy equipment, air conditioning and flashy gimmicks. We’re NOT about gimmicks or the latest fad. We’re not about trying to impress with you fancy buzz words like “core strength”, “functional training”, etc.

Our # 1 Focus Is On getting YOU Child Maximum Results In Minimal Time

This is Where We Excel.

We’re interested in working with supportive parents who have children that understand that success will take work and commitment on their part. It doesn’t matter if you’re not strong, not in shape or new to training. All you have to do is show up with passion and we’ll take care of the results.

We excel in working with the athlete who is undersized, underweight and weaker than the norms for his / her age. There is no athlete too weak to train here. We will get you stronger, faster, more explosive and more confident, that’s a guarantee.

There are parents and athletes who think they’re too good to train here. They are not humble or complain about the membership investment while they spend their money on expensive cell phones, fast food and other wasteful crap.

They let their ego get in the way of what they can TRULY become if they train with our expert Coaches.

The Underground Strength Gym has NO room for egos and rude people.

We ONLY accept athletes who have a burning passion to become a champion not just in sports, but in life as well.

No matter how weak or skinny you are…..

No matter how badly you’ve been embarrassed and beaten up by the competition….

NO matter how many times you’ve lost…..

We Can AND WILL change that.

YOUR Success is what we live, breathe and bleed for. You will not only be trained with the most effective training methods but you’ll also get critical nutrition and mindset support to accelerate your progress ten fold.

All you need to do is provide the commitment, dedication and consistency, we will provide the results, and that’s a promise.

We’ve NEVER failed at transforming our athletes into Champions. We over – deliver on results and prefer to prove it to you through ACTION because we stand behind our words.

It’s called Honesty & Integrity, a rare trait nowadays where everyone is trying to brain wash you through flashy ads, gimmicks, buzz words and fads.

As mentioned above, we guarantee results or your money back. We stand behind what we do and commit to your child’s success as if they are our own children. We care genuinely about your child’s success in sports and life, which is why we push our athletes to go above and beyond the norms.

There is NO way to cheat through sports OR life and expect to achieve above average success. To achieve success above the norms you must be willing to seek out the best methods to help you achieve your true potential. As a parent, you must be as motivated as your child is to help him / her achieve success.

This IS a serious commitment on your part as a parent as well.

As you know all too well, successful people are always doing the little things that non-successful people make excuse about.

The training at The Underground Strength Gym has been proven by hundreds of athletes as well as tens of thousands of athletes around the world who have sought out our training programs from out of state and even out of country.

Our training delivers rapid results in as little as 2 weeks through a unique blend of science, real world experience, trial and error dating all the way back to 1989. We walk the talk here, our success has come through well over 20 years of experience in training. We’ve made the mistakes so your child doesn’t have to. We take you straight to the road to success.

We’re talking about success on AND off the playing field as well as success that lasts a lifetime. The lessons your child will learn about life while training at The Underground will transform him / her into a leader in their future, NOT just through school athletics.

Transforming You Child Into A Champion Athlete Is NOT Our Only Goal.

We Help Your Child Achieve Success For A Lifetime.

Character, Confidence, Leadership, Honesty, Responsibility & Accountability – These are rare qualities amongst today’s athletes, and your child will learn them while training here. These traits are critical to his / her success in sports AND life, and we aim to help your child excel in ALL of these areas.

As an Underground Strength Gym Student, Excellence in all areas of your life is expected, mediocrity is rejected. Your efforts should be your best at all times, nothing less is accepted here. Anything less than your best will result in your membership being revoked. We don’t have the time or energy to waste on someone who is satisfied with average efforts and average results. We respect that you or your parents are investing your money to train here and that is something we take VERY seriously.

But, Not Everyone is Accepted into Our Program. Not because we are rude, but because we care about our athletes first and foremost. Anyone who brings down the energy or interferes with the passion of your goals ruins workouts for the dedicated athletes we train.

This includes athletes AND parents.

NOTE to Parents:

Please understand and respect that Our gym is strictly for athletes and coaches ONLY.

Parents are NOT allowed to come into our training area as this has proven to be a liability and an overall negative experience for both the athlete(s) and the coaches. No exceptions are allowed.

If you are a parent who is obnoxious, overbearing and interrupts our workouts you are not welcome here. Rude and overbearing parents make other athletes feel uncomfortable and ALWAYS ruin the workout for their son / daughter by intruding in their workouts and trying to tell the Coaches what is right or wrong.

I know you’ve seen these rude parents before, always screaming and yelling from the stands or the sidelines, telling the Coach what to do and how to do it.

Complaining about everything, blaming others for their child’s lack of success…..

We are experts and for this relationship to work you must trust us fully. Period. Our results have been proven time and again, years after year after year.

Your role as a parent is to support your child in coming here and letting us do the training.

At home we’ll need your support to help follow our nutrition guidelines as well as our extra flexibility and training to be done at home. Our program is a complete system and to make it work best the parents must help us as well as their child.

And Because We Are a Private Club, We Are Selective Of Who Is Accepted Into Our Program.

Above, Team Underground After A Summer Workout!

Only highly dedicated, highly motivated athletes are accepted into the program. No exceptions. This ensures that every athlete training at our gym compliments one another and helps raise the bar for one another.

Showing up late, complaining, making excuses, etc. is unacceptable at The Underground Strength Gym.

There are Coaches and Trainers flying in from around the world to learn about our Underground Strength methods in an effort to bring superior training back to their country, their gym and / or their team. This is YOUR opportunity to help your child get the best training possible. 

Above, Coaches From Around The World Travel Every Month To Learn Our Powerful, Underground Strength System. Your Child Has The Opportunity Of A Lifetime….

This is likely NOT an opportunity you had as a child and many former athletes always tell us they wished they had this opportunity when they were competing. Well, now is YOUR chance to give your child his / her best chance to succeed. To make it work, your support and commitment is needed.

Coaches fly in from Canada, The UK, Europe, Australia, The Caribbean Islands and More….. You Have An Opportunity Close To Your Home. To Think You’re Too Busy Or Your Child Is Too Busy Only Hurts You….. Time Flies TOO fast, give your child the opportunity to excel NOW, not next season, next week, next month, etc…..

Top Performing Teams such as The Lehigh University Wrestling Team & Blair Academy Wrestling Team seek out our coaching services as well. They KNOW we are the best when it comes to transforming athletes into stronger, faster, more explosive and more confident athletes.

“….. He has Loved every second of training at The Underground. I have never seen him dedicated to anything like he is to Underground Training.”


Dear Zach,

Thank you for everything you have done over the past few years for Jake. He will be leaving to go to Kings college tomorrow and begin the next phase as a college student athlete. We are really excited for him.

He has learned so much from you and the underground crew.

He has loved every second of training at the underground. I have never seen him dedicated to anything like he is to underground training.

I know he is going to miss it. He already plans to come during break. Please thank LaSalle for working with Jake as well.

He has been an inspiration to him as well. The kid only has great things to say about all of you. You have been an important part of his life and critical to his growth as an athlete and as man, thank you! Keep doing what you do!

Stephanie Daniel (Mom)


REMEMBER: We GUARANTEE results and you can expect to see AND feel the improvements both physically AND mentally in as little as 2 weeks. You have nothing to lose and everything to gain for your child.

How Does Our Membership Work?

We don’t offer sessions or count how often you train here.

Instead, we offer membership which means Commitment from YOU.

We understand that building championship athletes is a long term process, not a quick fix that happens in a few workouts. The fads and gimmicks promise those lies, we focus on Honesty & Integrity.

– All Training Options are Unlimited Training. Most of our high school athletes train with us 2 – 4 x week while most of our middle school athletes train with us 1 – 2 x week. Some middle school athletes are highly motivated to train more often than 2 x week and if they are emotionally / physically ready, we recommend this as well.

– All workouts are Coached and individualized according to your child’s sport, his / her weak areas and the time of year (off season / in season etc)

– Unlimited access to our gym ensures your child gets expert coaching each and every time he / she is here.

ALL memberships are billed via monthly EFT credit card.

Sorry, we do not accept check or cash on a monthly basis as this has proven to become a bill collecting process.

Our expertise is in Coaching & changing the lives of young athletes rather being bill collectors. We appreciate your understanding with this. Thank you.

Of Note: If price is your main concern then we are NOT the right program for you.

While other cookie cutter training facilities try to undercut everyone else with price it also reflects on their lack of expertise.

Our track record of transforming and helping hundreds of athletes that have walked through these doors does not fit us into the Wal Mart of Athlete Strength & Conditioning.

You can go to the local gym or health club chain that looks flashy and nice but you will never find the expertise and caring found here by our Underground Strength Coaches.

Life Long Lessons & Why Your Child Needs Something Unique and Different Than Their Competition….

ALL athletes need to get the edge over their competition if they want to truly excel and stand apart from the crowd. Their competition is already doing everything they are doing: attending athletic camps and clubs specific to their sport, training in their high school or collegiate weight room, etc.

If you’re doing the same training as everyone else how do you expect to set yourself apart from the pack? The truth is that you can’t, you are simply meeting the status quo.

Our methods are specifically geared towards the development of your child, turning weak points into strong points and developing overall athleticism specific to their sport.

We do NOT randomly throw together strength, speed, flexibility and conditioning programs hoping they will work.

Using tractor tires, Russian Kettlebells, barbells, sandbags and stones are only tools, nothing else. I’ve watched other Coaches and inexperienced trainers trying to use these tools with horrible technique and putting their athletes in great danger, ALL because they took the short road and copied someone from a video.

The Underground Strength System has been developed through 20 + Years training experience. Zach Even – Esh programs the training which has been modeled around the world by other Coaches.

Athletes from all around NJ travel to our locations and Zach has been the Strength & Performance Coach for Lehigh University Wrestling and Rutgers University Wrestling.

The methods used here did not come about from a weekend course or a few books like most other “coaches”. Our expertise has been crafted and molded, battle tested and proven with our athletes achieving above normal success time and again.

Why You Need an Expert For Your Child

The way we organize our training methods and training tools together is what separates us from the typical athlete development program and is exactly why our results quickly skyrocket the progress of any athlete who is part of our program.

Many parents and athletic coaches try to take the performance preparation into their own hands by getting the same training tools, thinking the equipment is the answer. Tools such as Russian Kettlebells, tractor tires, kegs, etc. Having the exercise tools does NOT qualify you as an expert.

For Example: My Father has Kettlebells at his house, this does NOT qualify him to train you or other athletes. I have a Football and Rugby ball in my house, this does NOT qualify me to Coach these sports.

Before being accepted into our program, Both the Parent AND athlete are interviewed because we not only require highly committed athletes, but we look for parents to be supportive of what we do and understand that commitment to their child will be a long term journey.


** Serious Inquiries Only Please **

Government Agencies / Specialized Seminars: Military, Law Enforcement and other Special Government Units are taken into consideration for acceptance depending on the nature and time frame of the project. This is an elite program and is taken very seriously. The program is constructed by Zach Even – Esh and lasts as long as necessary to achieve the desired goals of the specific group / unit.
