About Olaf Henning
Scientific thinking. Clear explanation. Practical context.
I am Olaf Henning, a German university-trained exercise scientist and sports scientist. I hold an M.Sc. in Clinical Exercise Science, an M.A. in Sports Science, and a B.Sc. in Sport and Performance. Fitness Simply Explained is where I translate training science, exercise technique, anatomy, physiology, nutrition, and research into clear educational content without hype, fear, or empty promises.
Understand instead of simply copying
Regular exercise was not always an obvious part of my life. As I began changing my own habits, simple practical questions gradually became scientific ones: What is actually supported? Why might one method work in one context but not another? Where does a useful explanation end and confident marketing begin?
Those questions led me into sports science and still shape this website. The aim is not to make every topic sound certain or effortless. The aim is to help readers understand the reasoning, evidence, limitations, and practical decisions behind fitness information.
What Fitness Simply Explained stands for
Good educational content should be understandable without becoming misleadingly simple. It should also show where the evidence is strong, where context changes the answer, and where general information reaches its limits.
Evidence, not repetition
Scientific claims should be checked against evidence that actually supports the specific statement. Uncertainty and limitations should remain visible rather than being edited away.
Context, not false certainty
Training, nutrition, and health questions depend on goals, background, capacity, preferences, available resources, and many other factors. Broad rules should therefore be treated carefully.
Practical guidance, not fitness magic
The goal is to offer useful priorities, understandable principles, and realistic next steps—not secret methods, miracle products, fear-based messaging, or guaranteed outcomes.
From a real question to a clear explanation
Every page should solve a defined reader problem, separate evidence from interpretation, and remain usable on a phone as well as a desktop.
Clarify the question
First, the search intent and practical problem are defined: what does the reader actually want to understand, compare, or do?
Evaluate the evidence
Relevant research, reviews, guidelines, position statements, and institutional evidence are assessed for quality, relevance, and fit with the specific question.
Explain without distorting
Technical language, mechanisms, and uncertainty are translated into accessible English without removing the conditions that make the information accurate.
Review and update
Content is checked for clarity, evidence quality, scope, responsive presentation, and changes in the scientific or practical context.
Credentials and additional education
Degrees and professional qualifications provide a foundation for scientific reasoning and practical work. They do not remove the need for careful interpretation, clear scope, or intellectual humility.
M.Sc. Clinical Exercise Science
University of Potsdam. Advanced study at the intersection of exercise science, health, prevention and rehabilitation, exercise physiology, testing, research methods, statistics, and applied science.
M.A. Sports Science
Otto von Guericke University Magdeburg. A broader sports-science perspective on training, health, performance development, methodology, planning, and scientific interpretation.
B.Sc. Sport and Performance
German Sport University Cologne. Foundational study in training science, movement, sport practice, performance development, and scientific work.
Fitness and personal training
Additional German education and certifications in fitness instruction, personal training, health-oriented exercise, and practical coaching.
Prevention and rehabilitation-oriented exercise
Additional German education and licenses in prevention-oriented exercise, rehabilitation-oriented exercise, health sport, and fall-prevention contexts.
Nutrition and sports nutrition
Additional valid German/European education in health-oriented nutrition, sports nutrition, and nutrition coaching.
Teaching and course development
Experience in adult education and the development of online and in-person learning formats for fitness, personal training, and nutrition education.
Fitness knowledge in connected learning paths
The website is designed so a practical question can lead to the relevant training, anatomical, physiological, nutritional, or scientific foundations.
Training science
Strength, endurance, flexibility, adaptation, training variables, recovery, and programming decisions.
Exercise technique
Exercise setup, movement control, target muscles, useful variations, and common execution problems.
Nutrition and supplements
Nutrition foundations, food context, ingredients, practical decisions, supplement evidence, and safety boundaries.
Muscle anatomy
Muscles, structures, functions, and movement explained for active adults and practical training use.
Exercise physiology
Processes inside the body translated into useful context for training, adaptation, fatigue, and recovery.
Evidence and critical thinking
Research interpretation, uncertainty, context, misleading claims, and the difference between a plausible story and supported evidence.
Evidence-informed does not mean medical treatment
Clear credentials also require clear limits. General educational content should never be presented as a substitute for an individual clinical assessment.
What the website provides
- General education about training, exercise technique, anatomy, physiology, nutrition, supplements, and evidence.
- Evidence-informed explanations, practical context, and transparent discussion of uncertainty.
- Clear reminders when a topic requires individual assessment or qualified medical care.
- Separation between free education, external services, and any future affiliate recommendations.
For curious readers, active adults, and fitness professionals
No academic background is required. Many pages are written to remain accessible to beginners while still providing enough context for students, trainers, and professionals.
For people who want to understand their training
- You want to train consistently without chasing every new trend.
- You want to understand why an exercise, method, or recommendation may be useful.
- You prefer structured learning over isolated fitness hacks.
For people who learn or work in fitness
- You are studying exercise science, fitness, training, or nutrition-related topics.
- You want clearer definitions, mechanisms, evidence quality, and scope notes.
- You work in coaching, education, sports science, or a related professional setting.

How is scientific evidence evaluated?
The goal is to evaluate evidence that fits the exact question, prioritizing suitable peer-reviewed research, systematic reviews, guidelines, position statements, and official scientific institutions. Quality, relevance, uncertainty, and practical limits are considered together.
Is artificial intelligence used to create content?
AI-supported tools may assist with spelling, grammar, wording, structure, or technical preparation. Subject-matter judgment, source selection, interpretation, final editorial decisions, and responsibility remain with Olaf Henning.
Does the website replace medical or individualized professional advice?
No. Fitness Simply Explained provides general educational information. It does not provide medical diagnosis, treatment, physical therapy, medical nutrition therapy, or individualized clinical assessment. Qualified care is appropriate for acute, severe, persistent, unclear, or medically relevant concerns.
