The Missing Evaluation for Identifying Strength Imbalances and Unlocking Performance
You assess clients all the time, but do you really know what you’re looking for?
How do you know which asymmetries or imbalances to fix and which to leave alone?
Do you wish you had a simple, practical, and reliable way to discover and improve the strength imbalances that are robbing your clients of performance and putting them at risk of injury?
A solution has arrived.
The Strength Symmetry Evaluation (SSE) is the first evaluation tool that allows you to quickly and easily identify and correct sub-optimal strength imbalances in your clients and athletes that lead to poor performance and increased injury potential.
Featuring 8 critical strength symmetry tests, the SSE is simple to perform, time-efficient, and it blends right into a training session seamlessly.
You’ll gain more clarity on where to focus your training program to deliver demonstrable results that your clients and athletes will love.
Spend less time guessing and more time progressing.


You’re not training it optimally unless you’re testing it properly.
If you’re a trainer or coach that works with clients or athletes, then you already know that almost everyone has some type of strength imbalance.
Maybe one arm is stronger, maybe their jump is higher when pushing off one side, or maybe they can perform an exercise perfectly on one leg and cannot complete a single repetition on the other.
Despite our bodies looking symmetrical, they almost never perform that way without some type of directed training. But you can’t train it if you can’t test it.
And how do you know which imbalances need to be fixed in the first place?
Unfortunately, it’s not as simple as just programming a handful of unilateral exercises and hoping for the best. That might actually make the problem even worse.
Instead, you need a need a way to identify which strength imbalances are actually a problem and give you a simple solution to correct them that works with any assessment process that you are already using.
The Strength Symmetry Evaluation does just that.
By using 8 easy to perform tests, you’ll be able to discover and correct sub-optimal strength imbalances, program and prescribe the right exercises and volume for ideal strength symmetry, and increase performance while reducing injury risk in clients and athletes.
Assessments VS Evaluations: You Need Both
Assessments and screens look at movement quality, but they don’t look at strength symmetry levels.
While assessments and screens are designed to tell you how your clients are moving, the SSE tells you their current areas of strength imbalances that need to be improved.
Assessments are performed with clients and athletes to tell us what exercises they can do safely and which variation is most suitable.
Evaluations are designed to tell us what exercises they NEED to do.

The best training programs need assessments and evaluations for optimal results. Think of them like a map and a compass: you need the compass (assessment) to find the right direction, but the map (evaluation) shows you the route to take.

The Strength Symmetry Evaluation (SSE) is the missing follow-up evaluation to any new client assessment process you may already be using.
What separates the best professionals from the rest is the best are always looking for ways to get even better results than they’re currently getting.
The SSE doesn’t attempt to change how you train or test your clients and athletes. It’s a tool to help you train and test better.
Plus, unlike other assessments and screens, each of the 8 different strength symmetry evaluations are not interrelated. The SSE is set up so that each individual test can be used as a stand-alone data source for training that you can keep coming back to.
This enables you to fill in the gaps to your own assessments by taking your favorite elements from the SSE and integrating them into your own system.
Streamline and Simplify Your Path to Results
To save time and avoid potential issues, you need data that tells you exactly what to do and demonstrates results without being too complicated or taking too long.
Many assessments require a long barrage of tests that require significant planning and eat up valuable time. The SSE does neither and can be incorporated into a training session so you can be effective and efficient.
The Strength Symmetry Evaluation gives you the valuable data needed to quickly identify and quantify the areas of weakness so you can be precise in where and how you build strength in your clients.
With each test only taking minutes to perform and score, you’ll be able to run the SSE time and time again to gauge progress demonstrate improvements. Your clients and athletes will see progress in real-time and be motivated to keep following the plan.
By implementing these 8 critical strength symmetry tests, you’ll know exactly which strength imbalances need to be corrected and how to do it.

Your SSE Questions Answered

Is the SSE appropriate for New or Advanced Professionals?
If you’re a new professional, you’ll appreciate the simple, straight-forward and step-by-step presentation on evaluation and performance training.
If you’re a seasoned professional, you will certainly recognize the effectiveness of the evaluation methods and will gain exciting new ideas, insights, and organizational strategies for programming.
So, no matter your experience level, the SSE has more than enough for you!
What equipment and space do I need?
You don’t need any specialized equipment to use the SSE, making it easy for virtually all professionals to implement, even with large groups.
Aside from basic free weights, all you need to perform the SSE are:
- A yard stick (from any hardware or home improvement store)
- An Airex style Pad
Who should the SSE be used with?
The SSE is suitable for use by all healthy, active individuals.
The SSE is especially beneficial for athletes who are involved in field, court and combat sports. And, for exercise enthusiasts who wish to maximize their functional performance.
When should the SSE be performed and how long does it take?
Each individual strength symmetry evaluation will take no more 10 minutes to complete, but it’s included as a part of your workout time.
The SSE is not like other assessments or screens that are performed all at once. Therefore, unlike other assessment and screens, you do not need to set aside extra time for “testing” days, which is a major time saver!
The best part is that each individual strength symmetry evaluation blends right into a training session. So, your clients and athletes will be getting a killer workout while you’re getting real-world data to keep creating better programs that drive better results.
Due to the challenging nature of each individual strength symmetry evaluation, it’s recommended that you only perform one or two of the ten total strength symmetry evaluations on a given day.
For the most accurate results, the particular strength symmetry evaluation you’re using that day should be done first in the workout, following a comprehensive warm-up.
Does Strength Symmetry really matter for most clients or athletes if they are already doing a mix of unilateral and bilateral exercises?
It’s not as simple as just doing random unilateral or bilateral exercises with good technique and hoping for the best. Random exercises produce random results.
To save time and avoid potential issues, you need data that helps you to program exercises specifically based on your clients’ needs, instead of just general ones.
Plus, your clients will be very impressed with how you’re able to provide them a higher level of service than they can get elsewhere.
Clients love tests like the SSE because it gives them verifiable results on their current needs, and can be repeated throughout the training process to prove to them your training is working to improve their performance.
Working with Nick Tumminello allowed me to see training in a whole new light. The way he was able to combine functional movement, flexibility, and strength training was like nothing I’d ever done before. Not only was I completely gassed at the end, but I found myself wanting more!
Nick Tumminello has my highest possible recommendation as a coach, trainer, educator, and subject matter expert. He is one of the most thoughtful and knowledgeable people in the industry and that comes through when he speaks.
It’s a rare person who knows the science in detail but has that eye for practically useful information – and Nick delivers big for people here. On top of all that, he has retained his humility and the sense that he doesn’t know it all either – and that makes him truly exceptional.
