Build Muscle.
Transform Your Physique.
Hypertrophy-focused personal training in Hitchin for serious physique change. Expert coaching, smart nutrition and body composition tracking that proves the muscle is going on.
Training Hard But Not Growing?
Building muscle takes more than just showing up. Without the right volume, progression and nutrition, your hard work stalls. Our coaches engineer the conditions for real, visible growth.
You train regularly but your physique won't change
You're not eating enough to grow — or eating wrong
Your programme lacks structure and progression
You want a visible, head-turning transformation
Why Muscle Building Works At Square One
Hypertrophy-specific coaching, smart nutrition and objective data so every kilo you gain is quality muscle.
Hypertrophy Specialists
Our coaches programme the volume, intensity and progression muscle growth demands.
Nutrition For Growth
We dial in the calories and protein your body needs to build, not just maintain.
Full Equipment Range
Free weights, machines and cables for complete, targeted muscle development.
Proven With Data
Body composition scans confirm you're gaining muscle, not just weight.
Data-Driven Muscle Building
We use body composition data to make sure your gains are lean muscle. Your programme and nutrition are continually refined around what your scans reveal.
Calorie and protein targets set for lean muscle gain
Progressive hypertrophy programming with tracked volume
Regular scans to confirm muscle-to-fat ratio
Recovery and sleep guidance to maximise growth
Medical-Grade Body Composition Analysis
Every member gets data, not guesswork. Our medical-grade body composition scan breaks down exactly what's changing inside your body — so your coaching is built on facts.
A level of body composition tracking rarely seen in local gyms and PT studios.
Muscle Mass
Track lean muscle growth in each segment of your body over time.
Body Fat %
See precise body fat percentage, not just a number on the scales.
Visceral Fat
Monitor the fat around your organs — a key marker of long-term health.
Hydration & More
Total body water, basal metabolic rate and segmental analysis.
Body composition analysis is for fitness tracking and coaching purposes and is not a medical diagnosis.
Know Your Numbers
Precise, repeatable measurements that show your progress in black and white.

Common Questions
How long until I see muscle growth?
Visible change typically appears within 8–12 weeks of consistent training and nutrition. Our body composition scans show muscle gains even sooner.
Do I need to eat a lot to build muscle?
You need the right amount, not just more. Your coach sets precise calorie and protein targets based on your scan data so you build muscle while minimising fat gain.
Can women build muscle here too?
Absolutely. Muscle building coaching helps women build lean, toned, strong physiques. Programmes are tailored to your individual goals.
What makes your approach different?
We combine hypertrophy-specific programming with body composition data, so every adjustment is based on proof your muscle is going on — not guesswork.
