Frequently Asked Questions

What is Workout Assistant?

Workout Assistant is an AI-powered fitness app that generates personalized workout plans, tracks your calories and macros, and helps you build consistent training habits. It supports multiple AI providers and works on iOS, Android, and the web.

How does AI workout generation work?

You describe your goals, available equipment, and fitness level, and Workout Assistant's AI builds a fully structured workout with exercises, sets, reps, and rest periods tailored to you. Each generated workout can be saved, edited, and scheduled directly inside the app.

What are AI credits?

AI credits power features like workout generation, exercise recommendations, and smart suggestions. Free accounts receive 10 credits per month at no cost. Pro subscribers get 75 credits per month, and additional credit packs are available for purchase — purchased credits never expire.

How does calorie tracking work?

Workout Assistant lets you log meals and individual foods with calorie and macro estimates. Your daily calorie budget is calculated from your BMR and activity level so you always know where you stand. Logged workouts automatically credit burned calories toward your daily balance.

What is BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic functions. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor that accounts for your daily movement and exercise. Workout Assistant calculates both automatically once you enter your height, weight, age, sex, and activity level.

How does the exercise library work?

The built-in exercise library contains over 70 exercises with instructions, form tips, target muscles, required equipment, and difficulty ratings. Tap any exercise name in your workout or schedule view to open its detail sheet. The library grows over time as new exercises are added.

How does workout scheduling work?

Workout Assistant includes a training calendar where you can assign workouts to specific days of the week. Scheduled workouts appear in your daily view so you always know what is coming up. Completing a scheduled workout logs it automatically and updates your weekly progress summary.

What are personal records?

Personal records (PRs) track the heaviest weight you have lifted for a given exercise across all of your logged workouts. When you beat a previous record the app celebrates with a PR banner on the completion screen. You can view your full PR history and progress charts for any exercise from the Progress tab.

How do progress charts work?

Progress charts show your weight-lifted history for each exercise over time, with selectable ranges of 30, 90, 180, and 365 days. Charts pull from your completed workout logs so they automatically stay up to date as you train. You can access the chart for any exercise by tapping its name in your workout history.

What is BYOK (Bring Your Own Key)?

BYOK lets you supply your own API key for Google Gemini or Anthropic Claude so you can use AI features without consuming app credits. At the BYOK subscription tier (Workout Assistant charges $2.99/month), your key is encrypted at rest and used only for your requests. This is ideal for power users who already have their own AI API accounts.

What is a collaborative home?

A home is a shared workspace in Workout Assistant that lets family members or training partners share AI credits and workouts. You can invite people to your home and they will draw from the same credit pool. Each person keeps their own private workout log and calorie diary while benefiting from shared resources.

Can I use the app on my phone?

Workout Assistant is available as a mobile app for iOS and Android, as well as a progressive web app you can use in any browser. Your data syncs automatically across all devices so you can log a workout on your phone and review progress on the web. Download links are available on the sign-up page.
