Not medical advice, not personal coaching. Metal Strength is a fitness tool. Its training programs, exercise instructions, set and rep targets, strength tiers, percentiles, one-rep-max figures, calorie and macro targets, and body-fat estimates are general guidance only — they are not medical, health, nutrition, physiotherapy, or supervised training advice, and they are not tailored to your health, history or injuries.
1. Programs are templates, not a personal plan
The ready-made training programs, the workouts the builder assembles, and any suggestion the app makes are generated from general training principles and templates. They are not written for you individually, no coach has assessed you, and the app cannot see your technique, fatigue, health history, or how a set actually felt. Treat every program as a starting point to adapt — adjust the load, the volume and the exercise selection to your own ability, and skip anything that is not right for you.
2. Estimates, not measurements
Strength standards are derived from population-based ratios and vary by exercise, sex, bodyweight, and age. One-rep-max values are calculated with established formulas (Epley, Brzycki, Lander, Lombardi, Mayhew, O'Conner, Wathan) and become less accurate at higher rep counts. Your real results may differ. Nothing here predicts what you can safely lift.
The same applies to everything else the app computes: estimated calories burned per session, training-split and muscle-focus breakdowns, weekly volume figures, and progress trends are approximations derived from what you entered. They are useful for spotting patterns over time, not for clinical or precise measurement.
The macro (nutrition) and body-fat calculators are likewise population-formula estimates. Calorie, macronutrient, and body-composition figures vary with individual physiology and measurement error — they are not nutrition, dietetic, or medical advice. Consult a qualified professional before making significant changes to your diet.
3. Exercise instructions and demonstrations
Exercise descriptions, the muscles listed for each movement, and the demonstration clips are simplified reference material. They cannot replace in-person coaching, they do not cover every variation or every body, and following them does not guarantee safe technique. If a movement is new to you, learn it with light loads and, where possible, with a qualified coach watching.
4. Consult a professional
Always consult a qualified physician or healthcare provider before starting, changing, or intensifying any exercise or nutrition program — especially if you have an injury, a medical condition, are pregnant, or have any doubt about your fitness to train. Stop immediately and seek help if you feel pain, dizziness, or discomfort.
5. Train at your own risk
Resistance training, and attempting maximal or near-maximal lifts in particular, carries an inherent risk of serious injury. You are solely responsible for training within your limits, using correct technique, proper equipment, and appropriate safety measures (such as a spotter or safety bars). Never use a number, a program, a streak, or a badge from this app as a reason to attempt a lift or a session you are not prepared for. Rest days and deloads are your decision, not the app's.
6. Records, standards and reference data
Any world records, community records, strength standards, or comparison data shown are compiled from publicly available sources or submitted by users, are approximate, and may be incomplete or out of date. Submitted records are reviewed on a best-effort basis and are not independently verified or certified by any federation. They are provided for interest only.
7. Your data is your record
History, charts and progress photos reflect what you entered and saved. We do our best to keep them safe and available, but the app is not a medical record or a certified logbook, and you should keep your own copy of anything you cannot afford to lose.
8. No warranty
Metal Strength is provided "as is", without warranty of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability.
9. Limitation of liability
To the fullest extent permitted by law, the developer of Metal Strength shall not be liable for any injury, loss, or damage of any kind arising from your use of, or reliance on, the apps, this website, or the information they provide. By using Metal Strength you accept these terms, together with our Terms of Service.
