Have you ever observed that one arm is able to lift a dumbbell more effortlessly than the other or that one leg is stronger while doing lunges? There are small variations between the two halves of the body. But in some cases, there are bigger or continuous variations that impact the way an exercise is performed.
Unilateral exercises, which train one arm or leg at a time, can help you identify these differences and work on them. By including the right movements in your routine, you can improve individual limb strength, coordination and overall training balance.
Strength disparities between left and right limbs, or interlimb strength discrepancies, arise whenever one part of the body works differently compared to the other limb during the same activity. For instance, you may discover that you are capable of doing more sets with your right arm than your left arm.
These differences can develop for several reasons, including natural body dominance, previous injuries, sporting habits and differences in movement experience. They do not always indicate a problem. In fact, the stronger side can vary depending on the exercise being performed.
The important thing is to understand whether the difference is consistent and whether it affects your exercise technique, comfort or performance.
You do not need complicated equipment to begin noticing differences between your limbs. Start by observing how each side performs during exercises that allow independent movement.
Exercises to Compare Left and Right Sides
Try comparing your left and right sides during dumbbell shoulder presses, single-arm rows, lunges or single-leg calf raises. Pay attention to the weight you can control, the number of repetitions you complete, your balance and whether one side struggles to maintain proper technique.
How to Keep Your Comparison Fair
For a more useful comparison, keep the following conditions consistent:
Research on measuring interlimb asymmetry highlights the importance of using consistent testing methods. Results can change depending on the exercise and measurement used, so one isolated performance difference should not be treated as a definitive diagnosis.
Unilateral vs Bilateral Training
Unlike bilateral exercises, which involve both sides working together, unilateral exercises focus on one limb at a time. This makes it easier to observe how each side performs without the stronger side contributing as much to the movement.
Exercises such as Bulgarian split squats, single-arm dumbbell rows, step-ups, and single-leg deadlifts can help develop strength and coordination independently on each side.
What the Research Suggests
Unilateral training also has a useful advantage: it can improve strength in the limb being trained while helping you practice balance and movement control. From research studies involving unilateral versus bilateral exercises, there is a suggestion that gains in strength are dependent upon the nature of the activity being performed. It is thus helpful for one to adopt both forms of exercise.
After establishing a discrepancy, start with increasing the attention paid to the weaker side without suddenly raising its volume too high.
Start With the Weaker Side
One strategy would be to start the training with unilateral exercises with the weaker side. Do all repetitions that this side can handle in control, then do the same number for the stronger side. This way, the stronger side won’t be working unnecessarily harder.
For instance, if your left arm makes eight controlled dumbbell rows, make eight repetitions with your right arm too, although it is able to do more.
Progress Gradually
Choose a manageable weight and focus on technique, control and a comfortable range of motion. Progress gradually as both sides become more capable. Avoid automatically doubling the sets for the weaker side, as additional volume is not always necessary and may increase fatigue.
When to Seek Professional Advice
If you experience pain, sudden weakness or a noticeable loss of function, seek advice from a qualified health professional rather than trying to correct the issue through exercise alone.
You can introduce unilateral movements into your existing routine without replacing every bilateral exercise. The following options provide a practical starting point:
Start with a manageable number of sets and repetitions, concentrating on controlled movement rather than lifting the heaviest possible weight. If you need help organizing these movements around your other exercises, read our guide on how different rep ranges affect strength, muscle growth and endurance.
If you prefer to train with an instructor, the group classes at Kahma include lower body workouts, upper body workouts and core workout classes, which can complement your single-limb training.
Track Your Progress
Improving left-right strength differences takes time and consistent practice. Record your weights, repetitions and how each side feels during training. Review your progress over several sessions instead of judging improvement from a single workout.
Choose the Right Support and Training Environment
If you are looking for personal training Shepparton has to offer; professional guidance can help you learn correct exercise techniques and organise a programme around your individual goals. At Kahma 24/7 Gym, personal trainers are available, and you can contact the team to ask about sessions.
When comparing fitness clubs Shepparton, Victoria residents can choose from, consider whether the equipment and training environment support both unilateral and bilateral exercises. A gym Shepparton members can access 24/7, with free weights, cardio equipment and group classes, making it easier to fit balanced training into your week. You can learn more about Kahma 24/7 Gym or read more training guides on the Kahma blog.
You can also explore Kahma 24/7 Gym membership options to learn more about available training access.
Remember, the goal is not necessarily to make both sides perform identically in every exercise. It is to develop better control, strength, and confidence while addressing differences that affect your training. With a balanced program and gradual progression, unilateral exercises can become a valuable part of your fitness routine.
