Body Muscle Matters
Evidence-aware fitness advice for building muscle and strength.
About Callum Todd
I’m Callum, a gym and fitness enthusiast based in Brighton, UK. I built Body Muscle Matters to share what I’ve learned through years of training, testing gear, and reading far too many studies on muscle physiology, so you don’t have to wade through the noise yourself.
Brighton Base, Transatlantic Perspective
I’m based in Brighton but travel to the United States, both East and West Coast, several times a year. That regular back-and-forth means I’ve trained in gyms on both sides of the Atlantic and kept up with the supplements, equipment, and fitness culture in both markets. Where a post draws on US products or prices, you’ll see dollar figures ($). UK-focused content uses pounds (£). It’s that straightforward.
How I Got Here
I got into serious training in my mid-twenties after a fairly unremarkable gym phase that amounted to showing up, doing the same three exercises, and wondering why nothing changed. The turning point was slowing down, actually reading about how muscle works, and treating the gym like a skill to learn rather than a chore to tick off.
From there it snowballed. I started digging into the science behind hypertrophy, comparing training programmes, testing recovery tools, and spending more money than I care to admit on supplements, some worthwhile, many not. After a few years of accumulating that trial-and-error knowledge, it made sense to write it down somewhere useful.
What This Blog Covers
Body Muscle Matters is focused on practical, evidence-aware content for people who take their training seriously, whether that’s someone in their first year at the gym or someone who’s been lifting for a decade and wants to refine their approach.
Topics covered include:
- Strength training principles and muscle science
- Bodybuilding programming and technique
- Fitness accessories and technology
- Supplement and nutrition guidance
- Product reviews, honest assessments, not hype
This site does not cover competitive sport, clinical nutrition, or medical advice. If something has health implications, I’ll flag it clearly and recommend you speak to a qualified professional.
How I Write
I’m not a personal trainer or a dietitian. I’m self-taught, and I try to be upfront about that throughout the site. When I cover a topic, I read widely, cross-reference sources, and write from a position of informed interest rather than professional authority. Where the evidence is mixed or the subject goes beyond my knowledge, I say so.
Some posts include affiliate links. That means if you buy something I recommend, I may earn a small commission at no extra cost to you. It doesn’t change my assessments. If something isn’t worth buying, I’ll say that too.
My aim is for every article to answer the question you actually came with, give you enough context to make your own decision, and not waste your time getting there.
