Question: I need a fitness tool that provides access to a large database of exercises and allows me to track my progress and optimize my performance.

One of the top options is Alter, which uses genetic data from DNA tests and biometric data from wearables to create personalized workout routines, recovery plans and nutrition advice for your specific fitness goals. It offers daily workouts, recovery itineraries, sleep optimization advice and real-time heart rate monitoring during exercise, so it's a powerful tool for maximizing performance and tracking progress.

Another top contender is Workout Tools, an AI-powered personal trainer that offers customized workouts based on your needs. With a library of more than 800 exercises, the service lets you find workouts tailored to your goals and preferences. It also includes tools like injury tracking, personal records and detailed workout plans, so you can easily focus your fitness routine.

For a digital workout experience, Coachify offers animated video demonstrations of exercises and lets you log sets and track form. The app uses AI to track progress and generate reports on strength gains, and it offers personalized coaching through an AI trainer, so it can be a supportive option for people of all fitness levels.
