About MuscleData
MuscleData is an independent site dedicated to strength training and sports nutrition. No hidden sponsors, no disguised paid content — only data, validated formulas, and rigorously written content.
Our mission
Provide the tools and knowledge every practitioner needs — beginner or advanced — to make informed decisions about their training and nutrition. No bullshit, no miracle products, no commercial pressure.
Our values
Science-backed
Every calculator uses scientifically validated formulas (revised Harris-Benedict, Mifflin-St Jeor, Lorentz, Devine…). Every article cites its sources and distinguishes what studies prove from what is still debated.
No bullshit
No unrealistic promises, no miracle supplements, no extreme diets. MuscleData covers the fundamentals that work: progressive training, adequate protein intake, recovery, and consistency.
