Find out if you are really building muscle using DEXA Scan body composition data, strength tracking, and evidence based progress indicators.

Building muscle takes time, consistency, and the right strategy, but one of the hardest parts is knowing whether your training is actually working. Your weight may stay the same, your pump may look good some days, and your clothes may feel different, but none of these are reliable indicators by themselves.
At Kalos, we help clients track real muscle growth using highly accurate DEXA Scan data. When you measure lean mass directly, you do not have to rely on guessing, mirrors, or gym bro science.
Here is how to know with confidence if you are truly building muscle.
Muscle grows slowly, especially for anyone who is not a complete beginner. You may gain:
That is so subtle that you will not see it clearly in the mirror or on the scale for weeks. Water retention, pump, food weight, and glycogen all make visual tracking extremely unreliable.
You need objective feedback.
A DEXA Scan measures your lean mass precisely in:
This makes it the most reliable method to confirm:
If your lean mass goes up on a DEXA scan, you are building real muscle. No other method is as consistent or accurate.
This is the gold standard. Even small changes matter.
If you are getting stronger in compound lifts, you are likely building muscle.
Examples include:
Strength alone does not guarantee muscle growth, but it strongly correlates with it.
Improved recovery and less soreness after similar workouts indicate improved muscle adaptation.
If you consistently hit your protein and calorie targets, conditions for growth are present.
Progressive overload is essential.
You should consistently increase:
You may not be building muscle if you notice:
These issues often show up in composition data long before you see them physically.
Measures lean mass changes directly.
Record your lifts, reps, and weights weekly.
Not reliable alone, but useful over long periods.
Arms, legs, and torso measurements can show changes, though they include fat and water.
If strength goes up while body fat goes down, you are likely building muscle efficiently.
Muscle building depends on:
A DEXA scan shows whether all of these variables are working for or against you.
A Kalos client trained four times a week but was unsure whether they were gaining muscle. Their first DEXA scan showed baseline lean mass. After increasing protein intake, improving sleep, and structuring their training for progression, their next scan showed:
They were finally able to confirm real muscle growth instead of guessing.
You cannot trust the scale or the mirror to tell you whether you are building muscle. The most reliable way to know is through DEXA Scan analysis backed by strength tracking and consistent nutrition.
When you measure your progress objectively, you stay motivated, avoid wasted effort, and make smarter decisions that lead to long term transformation.
