Strength Training Terms, Explained in Your Language

Strength training runs on jargon. RPE, e1RM, ACWR, the accumulation phase, a training max, a freestyle session. If you are new to the sport, or reading in a second language, that vocabulary is a wall between you and the app. A glossary built into the app, with plain definitions you can read in your own language, takes the wall down.

The jargon problem

Every serious training tool is dense with terms of art, and most of them assume you already know what they mean. That is fine for a coach who has lived in the sport for years. It is a real barrier for a newcomer deciding whether an app is worth their time, and a bigger one for the many lifters who read English well enough to train but do not know the English word for a specific lift or concept. The fix is not to dumb the app down. It is to explain the words, clearly, right where you meet them.

A glossary that lives in the app

Ægir Iron has a searchable glossary of the terms the app actually uses, from the training-science vocabulary (RPE, estimated 1RM, relative intensity, acute-to-chronic workload) to the app-specific words (a freestyle session, a cluster set, the mesocycle phases). Each entry is a short, plain definition written for how the term is used in the app, not a generic dictionary line. You open it from the More menu, type a word, and read what it means. No leaving the app, no separate search.

Read the terms in your language

The glossary is multilingual. A language selector sits at the top of the search sheet, and every definition can be read in your language: English plus French, Spanish, German, Italian, Portuguese, Swedish, Norwegian, Dutch, Polish, Russian, and Chinese, with more added over time. Search is accent-aware and language-aware too, so you can type a term the way you know it and still land on the app's word for it. That last part matters: it is not only a translation, it is a bridge from the vocabulary you already have to the one the app uses.

Find a lift by its name in your language

The same idea reaches the exercise library. The exercise search matches not just the canonical English name but a set of aliases: common abbreviations like RDL and OHP, and names in other languages. Type sentadilla and the squat comes up. Type without accents and it still matches. The exercise still saves and charts under one canonical name, so your PRs and analytics stay clean, but you can find it however you think of it.

Ask your Assistant Coach in your language

The optional Ægir Assistant Coach adds a third layer, and it replies in your language by default. Because it reads your own logged results and analytics, you can ask it to explain a term or interpret your numbers, and it answers conversationally: why your estimated 1RM moved, whether your load is climbing too fast, what a block accomplished. You can also just talk to it to get things done, logging a workout, updating a max, or building a program, by typing or speaking in your language, so the model maps what you said onto the app for you to confirm. Where the glossary defines a word and the exercise search finds a movement, the assistant lets you understand and run your training in your own words. It is a paid add-on, off by default, and it sits above the two free layers rather than replacing them.

So the app meets a non-English speaker in three ways: exercise search that matches a lift by its name in your language, a glossary that defines every training term in your language, and the assistant that explains and interprets your own training in your language.

To be clear about what this is and is not: the app's interface is currently in English. But the parts that actually gate comprehension are covered, the terms, the exercise names, and the interpretation of your own numbers. Full interface translation is a larger effort, and if you would like your language added or a translation improved, a quick note to angela@aegirlab.com goes a long way.

Where Ægir Iron fits

Ægir Iron is a strength-training platform for powerlifters, weightlifters, strongman competitors, calisthenics athletes, and the coaches who program for them. The glossary and the multilingual exercise search are free and built in, and the assistant is an optional upgrade, together making a genuinely deep app approachable rather than intimidating. It is education and training information, written to help you understand your own training and the words it uses.
