About Rep Labs Fitness
Rep Labs Fitness is the training-guides site from Rep Labs, an app for lifting, running, yoga, Pilates and food tracking made by HLB Strategies LLC in Georgia, USA. The guides answer the questions people ask us most, often the ones that started on our TikTok and Instagram posts.
How a guide is made
- Research first. Each guide starts from the studies, position stands and health-body guidelines on the question, and every number links to its source at the bottom of the page.
- Checked against the source. Numbers are checked against the paper, not a summary of it. If a claim can't be traced to a source, it doesn't go in.
- Honest about limits. We say when a study is small, short, or only looked at one group of people, and we label everyday coaching advice as advice rather than research.
- Written with AI tools, edited by Rep Labs. We use AI to help research and draft, and nothing is published without the source checks above.
- Kept up to date. Each guide shows the date it was last updated.
About Rep Labs
Rep Labs makes this site, and the guides end with a short note about the app. The guides are written to be useful whether or not you ever download it. Rep Labs is free on the App Store for iPhone and Apple Watch, with Android coming soon.
Not medical advice
These guides are general information for healthy adults. If you have pain, an injury, a medical condition or are pregnant, talk to a doctor or physiotherapist before changing how you train or eat.
