Struggling to Gain Muscle? Here’s Why

If you’ve been lifting, eating right, and still feel like your muscles aren’t growing, you’re not alone. Muscle gain is often harder to measure than weight loss — the scales don’t move much, and progress can feel invisible week to week.

The real issue: Everyone responds to training differently.

Some bodies thrive on heavy, low-rep strength work, while others grow better with higher-rep endurance training. Some need more recovery, others need more fuel. Standard “one-size-fits-all” plans often fail to deliver.

 

At TELOMYX, we use advanced body composition, metabolism, and fitness testing to reveal how your body actually responds. A DEXA scan shows where you’re gaining lean muscle (and where you’re not). An RMR test uncovers whether you’re eating enough to grow, and VO₂ Max testing shows if your cardio training is supporting — or holding back — your gains.

 

Instead of guessing, you get hard data that tells you whether to push heavier weights, increase volume, adjust nutrition, or improve recovery — so every session drives real muscle growth.

Use the same advanced performance data professional athletes and celebrities rely on to maximise their muscle growth and strength gains.

Our Three Core Tests for Muscle Gain

DEXA Scan for Muscle Gain

Nothing’s more frustrating than training hard and not seeing your muscles grow. A DEXA scan reveals whether you’re truly building lean mass, where that muscle is developing, and if your training is protecting your progress.

VO₂ Max Test for Weight Loss

Nothing’s more frustrating than training without progress. Learn your fat-burning heart rate zone so you can train smarter, burn more fat, and see results faster.

VO₂ Max Test for Muscle Gain

A VO₂ Max test reveals how efficiently your body uses oxygen, so you can optimise recovery, train in the right zones, and create the endurance base needed to fuel harder lifting and sustained muscle growth.

Resting Metabolic Rate (RMR) Test for Muscle Gain

Struggling to build muscle even while eating more? Your metabolism may not match the standard formulas. An RMR test shows your true calorie needs so you can fuel growth and finally see results.

TELOMYX Case Studies

Jono - Breaking Through a Muscle-Gain Plateau

Jono had been training hard for months, but couldn’t see any changes in the mirror or on the scale. What he didn’t realise was that he was making progress — just not in a way that ordinary scales could show.

 

A DEXA scan revealed that Jono’s lean muscle mass was increasing while fat was gradually dropping, proving his efforts were paying off. But the real breakthrough came from his RMR test, which showed his metabolism burned 1,823 calories a day — higher than he’d assumed. By adjusting his nutrition to match his actual burn, he finally gave his body the fuel it needed to grow.

 

With accurate data guiding both training and diet, Jono was able to break through his plateau, see measurable gains, and train with the confidence that every session was moving him forward.

Sam, Manchester

"I used to eat based on online calculators, but I was constantly either overeating or undereating. My RMR test showed exactly how many calories my body actually burns, and pairing that with my DEXA results helped me finally fuel properly for muscle growth. I’m eating smarter, not guessing anymore — and the gains are showing."

Rachel, Liverpool

"The scale never seemed to move, and I felt like I was spinning my wheels. My first DEXA scan proved I’d been building lean muscle while dropping fat, even though my weight stayed the same. That hard data kept me motivated and showed me that my training was working."

Tom, Preston

"I thought I was putting on solid muscle, but my DEXA scan showed most of the weight I’d gained was actually fat. That was a wake-up call. With the scan results and my RMR test, I learned how to fuel properly for growth without overshooting on calories. Since then, I’ve been adding lean muscle instead of just piling on fat."
