Structural balance in resistance training refers to achieving strength symmetry across muscle groups and movement patterns. Originally a concept from Soviet sports science and later popularized in the West by Charles Poliquin, structural balance emphasizes the importance of proportional strength development. The primary benefits include enhanced performance, improved results, and reduced injury risk.

What is Structural Balance?
Structural balance is a strength training approach that aims for balanced muscle development. This balance prevents one muscle group from overpowering another, reducing undue strain on joints and connective tissue. You are comparing the loads lifted in a variety of lifts to look for certain lifts that are approximately 10% or more from their ideal ratio.
Structural balance in resistance training is similar to how a car performs when driving on the road. Imagine a car where different amounts of power are applied to each of the four tires. This imbalance would cause uneven wear on the tires, reduce the car’s overall performance, and place stress on its suspension and alignment. In the same way, structural imbalances in the body can impair performance, cause strain, and lead to wear on joints and muscles over time.
Similar to the car analogy, the different muscle groups in your body should be in relative balance to each other. The strength of your squat, the amount of weight you can lift, should be in a certain ratio to how much you can overhead press. Closely maintaining this ratio will ensure your upper body and lower body are relatively balanced. The same importance occurs when comparing the upper body muscles that perform pulling movements and those that perform pushing movements. There are currently 40 different lifts in Higher Endeavors’ Structural Balance tool.
What is the Master Lift?
The Master Lift is a foundational exercise used as a benchmark in structural balance assessments. Typically, it refers to a primary, multi-joint compound movement, such as the back squat or bench press, that serves as a reference point for evaluating strength ratios across other related lifts. These ratios are critical for identifying and addressing muscular imbalances, ensuring that all muscle groups develop proportionally.
In structural balance calculations, the Master Lift is the cornerstone. By establishing a baseline for this lift, practitioners can derive optimal strength targets for complementary and accessory lifts. For example, the strength of a back squat can be used to calculate proportional strength levels for the front squat, deadlift, or Peterson Step-Up, ensuring that all major lower-body muscle groups are adequately developed. Similarly, the bench press can guide appropriate targets for exercises like the overhead press, pull-ups, or dumbbell rows. You can even compare upper body to lower body exercises to make sure those are in balance.
The role of the Master Lift in structural balance is twofold:
Diagnostic Tool: By comparing performance in the Master Lift to other movements, users can identify weaknesses or imbalances in specific muscle groups. For instance, if the back squat is disproportionately stronger than the deadlift, it may indicate a posterior chain weakness that needs to be addressed.
Training Guide: Structural balance calculations based on the Master Lift help set clear, measurable targets for improving performance. These targets guide programming, ensuring that weaker areas receive appropriate attention without neglecting overall progress.
Using the Master Lift as the foundation ensures that training remains balanced, efficient, and goal-oriented. It not only supports optimal performance in the lift itself but also enhances movement mechanics, reduces injury risk, and promotes long-term strength development across the entire body.
How Does Structural Balance Work?
Structural balance assessments determine whether specific muscles or muscle groups lag in strength relative to others. The concept of structural balance can be implemented using strict testing protocols where you test your 1-5 repetition max for one or more of the lifts every 4-8 weeks. You can also take a more informal approach where you are aware of your 5-10 repetition maximum in certain lifts and consistently compare those numbers to the loads you lift in your training sessions.
By measuring and targeting these imbalances, users can develop balanced strength, fostering greater resilience and efficiency in movement.
Why is Structural Balance Important?
Performance Enhancement
Balanced strength enables the body to operate as a cohesive unit, allowing for greater power output, stability, and control in movements. This leads to improved athletic performance and efficiency in both dynamic and static activities.
Reduced Injury Risk
Imbalances often lead to compensatory movement patterns that increase stress on joints, ligaments, and tendons. Maintaining structural balance mitigates this risk by promoting proper joint alignment and movement mechanics.
Optimized Results
Addressing structural imbalances ensures that all muscle groups can engage fully, leading to better results in muscle growth, strength gains, and overall fitness improvements.
Enhanced Posture and Movement Quality
Balanced muscles support proper posture, reducing the likelihood of chronic issues caused by muscle tightness or weakness.
Long-term Joint Health
By distributing loads more evenly across muscles and joints, structural balance preserves joint health, extending training longevity.
When to Address Structural Balance
Structural balance should be a priority for anyone starting a resistance training program, as well as those experiencing performance plateaus, recurring injuries, or chronic pain. Regular assessments can help users stay on track.
Action Steps
Formal Assessment Protocol
Testing your structural balance in this way involves, ideally, setting aside one training session at the beginning/ end of a training cycle that will you spend on assessing the loads you can lift in certain lifts. You should be relatively well recovered from previous training sessions, approximately 72 hours of recovery, before performing the assessment.
Prior to your assessment session, you want to look at your training history, the structural balance lifts, and use your intuition and experience to determine which exercises would be most important to test. To effectively select lifts to test, you want to think about your goals and your needs analysis relative to those goals. You also want to think about known injury and performance issues you have to help you select exercises that may reflect those issues. Ideally you want to select 3-5 exercises from the structural balance exercise list to test.
Now, you want to select your Master Lift, which will be the lift that all of the other lift calculations are based on. This lift should have the biggest correlation to your goals or be the most physically demanding of the lifts you have chosen. For example, if your goal is to address your chronic lower back pain, you may decide that a variation of a Good Morning, Deadlift, or Squat might be the most appropriate Master Lift. If unsure what to choose as your Master Lift, a compound movement you are comfortable executing is probably your best option, i.e. squat, bench press, standing overhead press.
To start off your assessment session, you want to go through a thorough warm-up following good warm-up principles. After your warm-up you want to select the first of the structural balance lifts, ideally the lift that is the most demanding on your nervous system. Think about the exercise that uses the most muscles or the exercise that you plan on using the most load. For example, test the barbell back squat before you test the incline dumbbell bicep curl. This lift will also potentially act as your Master Lift for this Structural Balance assessment.
Next, you should have already selected the number of repetitions that you will consistently use to test all lifts, unless the lift specifies a different repetition number. For most people, testing 3-5 repetitions is ideal. Competitive athletes or those with specific performance requirements may benefit from testing true one repetitions maximums.
You now want to select the load for your first lifting set. This should be relatively close to the amount you think will ultimately be your maximum for the lift, but not quite that amount yet. It should take you 3-5 sets to get to your maximum load. This will ensure your soft tissue and nervous system are thoroughly warmed up and prepared to lift the heavy loads. Learning to choose your starting loads and progressing between each set will improve with more resistance training experience. You should rest 3-5 minutes in between each testing set to allow your muscles and nervous system to recover.
On your final testing set, you should have selected a load that will allow you to complete the targeted repetitions with no repetitions in reserve. At that point, you want to record that number. You then want to repeat the same procedure with the remaining lifts you have chosen, recording the final load lifted for each lift.
Once you have tested all of your lifts and recorded the numbers, you are now ready to input them into the Structural Balance tool. Start by entering the load used for the Master Lift you selected. Then click the Calculate button. You will now see a table of exercises and the corresponding load that is calculated, using Structural Balance ratios, that your Master Lift.
Next, you should find the remaining lifts that you performed as part of your assessment and compare the loads you lifted to the loads calculated. If the two numbers are within approximately 10% of each other, you are relatively balanced for that lift. If the load you lifted is greater than the calculated load, then you are stronger in that lift than the structural balance ratio suggests. If, however, the load you lifted is lower than the calculated number, then you are weaker in that lift and this may be an area that needs to be addressed.
Informal Assessment Protocol
The informal assessment process takes a more on-going, subjective approach to using Structural Balance testing. This approach views each training session as an opportunity to evaluate your Structural Balance. Every time you perform an exercise that is part of the Structural Balance exercise list, you can compare the loads you lifted relative to the calculated loads found within the Structural Balance tool. The most important thing to remember is that you must always compare loads to exercises performed for the same number of repetitions.
If, as part of your program, you perform 3 sets of 8 repetitions in the squat and also the bench press, assuming relatively equal effort, you can compare the loads of those two exercises using Structural Balance. However, if, for one of the exercises, you performed 3 sets of 5 repetitions and the other was for 3 sets of 8 repetitions that is not valid comparison.
The Formal Assessment is used at the end/ beginning of a training cycle to be used to select the imbalances that need to be addressed for the next training cycle. Using the informal approach will require you to constantly pay attention to imbalances and make programming decisions based upon the observations you have made throughout that process. There is no correct approach to this process. You have to think about your own preferences and tendencies to determine whether you like a more structured approach to your programming, or if an unstructured approach works better. As with all aspects of our approach, the plan consistently implemented is more important than the perfect plan that is rarely implemented.
Example Scenario: Applying Structural Balance Principles
Meet Sarah, a Recreational Athlete
Sarah is a 35-year-old recreational athlete with a goal to improve her overall strength and athletic performance while reducing her recurring knee pain during running. She has been training regularly for a year but feels her progress has plateaued. After learning about Structural Balance principles, she decides to incorporate them into her training.
Step 1: Assessment Process
Sarah begins with a Structural Balance assessment by testing her strength in key lifts:
Master Lift Test: Sarah selects the back squat as her Master Lift and performs a 3-rep max under controlled conditions. Her 3-rep max is 135 lbs.
Strength Ratio Calculations: Based on her back squat results, she calculates the expected strength ratios for complementary lifts:
Front Squat: ~85% of her back squat (115 lbs)
Deadlift: ~120% of her back squat (160 lbs)
Bulgarian Split Squat (per leg): ~40% of her back squat (54 lbs)
Testing Complementary Lifts: Sarah tests her actual performance on these complementary lifts:
Front Squat: 90 lbs (significantly below target)
Deadlift: 170 lbs (above target)
Bulgarian Split Squat: 35 lbs (significantly below target)
Results: Sarah’s assessment reveals imbalances. Her posterior chain is strong (deadlift), but her anterior chain (front squat) and unilateral leg strength (Bulgarian split squat) lag behind. This imbalance could contribute to her knee pain and limit her performance improvements.
Assess Current Strength Ratios: Tools such as ratio-based strength assessments can help identify areas that need focus.
Set Targeted Goals: Define strength goals for muscle groups that show significant imbalance.
Incorporate Targeted Exercises: Add exercises that specifically address weaker muscle groups while maintaining overall training balance.
Monitor Progress: Regularly reassess strength ratios to track improvements and adjust the program as needed.
Step 2: Program Design Based on Results
Using her assessment data, Sarah creates a 6-week training program to address her imbalances while maintaining overall strength:
Primary Focus: Anterior Chain and Unilateral Strength
Front Squat: 4 sets of 6 reps, progressively increasing load weekly.
Bulgarian Split Squat: 3 sets of 8-10 reps per leg, focusing on control and depth.
Glute-Ham Raises: 3 sets of 8-10 reps for posterior chain support.
Accessory Work: Balance and Core Stability
Lunges: 3 sets of 10 reps per leg to improve dynamic balance.
Plank with Knee Drive: 3 sets of 30 seconds to build core strength and stability.
Mobility and Recovery
Dedicated mobility drills for the hips and knees 3x per week.
Regular foam rolling and stretching for tight muscles.
Step 3: Reassessment
After six weeks, Sarah reassesses her lifts:
Front Squat: Improved to 110 lbs (closer to target).
Bulgarian Split Squat: Improved to 50 lbs per leg (near target).
Deadlift: Maintained at 170 lbs.
Outcome: Sarah’s knee pain has significantly reduced, and her running feels more powerful and efficient. By addressing her imbalances, she not only improved her strength symmetry but also enhanced her athletic performance and reduced her risk of injury.
