How to Fix Muscle Imbalance

Muscle imbalances are more common than most people think. One side feels stronger than the other, certain exercises feel awkward, or your posture looks uneven in photos. These imbalances do not just affect your appearance, they can limit strength, slow progress, and increase injury risk.

At Kalos, we use DEXA Scan technology to identify muscle imbalances with precision. Because DEXA measures lean mass in each limb separately, it can reveal even small strength and size differences that are hard to spot on your own. Once you know which muscles need attention, fixing imbalance becomes simple and highly effective.

What Causes Muscle Imbalance?

Muscle imbalances develop for several reasons, including:

  • Favoring one side during daily activities
  • Poor exercise technique
  • Postural habits like leaning or slouching
  • Previous injuries that change movement patterns
  • Overtraining certain muscles while neglecting others
  • Dominant limb compensation during lifts

Most imbalances are subtle at first but grow over time unless corrected.

Why Muscle Imbalance Matters

A slight imbalance may seem harmless, but over time it can cause:

  • Reduced strength and power
  • Increased joint stress
  • Higher injury risk
  • Uneven fat distribution or shape
  • Poor athletic performance
  • Slower progress in compound lifts

Fixing imbalance improves both aesthetics and performance while protecting your long term joint health.

How DEXA Scans Help Identify Muscle Imbalance

A DEXA Scan shows exactly how much lean muscle mass you have on each side of your body. It provides a breakdown of:

  • Right vs left arm muscle
  • Right vs left leg muscle
  • Upper vs lower body balance
  • Total vs regional lean mass

This accurate measurement helps you target the lagging side with specific exercises rather than guessing.

How to Fix Muscle Imbalance the Right Way

1. Use Unilateral Exercises

Training each side individually prevents your dominant limb from taking over. Include exercises like:

  • Single arm dumbbell press
  • Single arm rows
  • Bulgarian split squats
  • Single leg Romanian deadlifts
  • Single arm lat pulldowns
  • Single leg leg press

Do more work on the weaker side until balance improves.

2. Start With the Weaker Side

Always perform unilateral exercises beginning with the weaker side. Match reps and weight on the stronger side, not the other way around.

3. Increase Volume on the Lagging Side

Add an extra set or 2 for the side that needs more development. This helps stimulate more growth without overworking the dominant side.

4. Improve Your Technique

Poor form creates imbalances faster than anything. Focus on:

  • Slow, controlled reps
  • Stable posture
  • Full range of motion
  • Using the target muscle, not momentum

Recording your lifts can help identify compensations.

5. Strengthen Your Core and Posture

A weak or asymmetrical core can cause imbalances in both upper and lower body. Include planks, anti rotation movements, and controlled mobility drills.

6. Stretch and Mobilize Tight Muscles

Sometimes the stronger side is tight rather than strong. Increasing flexibility can restore balanced movement patterns.

7. Track Progress With DEXA Scans

Monthly DEXA scans reveal whether the weaker side is catching up. When the lean mass numbers begin to match, the imbalance is truly fixed, not just felt.

How Long Does It Take to Fix Muscle Imbalance?

Most people see improvement within 4 to 8 weeks, depending on consistency and severity. Severe imbalances may take longer, but with proper training and tracking, progress is predictable.

The Bottom Line

Muscle imbalances are normal, fixable, and often easy to correct once you have the right data. By combining unilateral training, smart technique, and DEXA Scan tracking, you can restore balance, prevent injury, and improve performance across every lift.
