It suits both beginners who want ready-made plans and experienced lifters who like to track every set and fine-tune programming.

Core features include a library of well over a thousand exercises with form instructions, mobile and smartwatch logging, muscle-recovery breakdowns, one-rep-max calculations, charts for workout duration and lifting volume, and a large community for accountability and shared routines.

Typical use cases include running a structured hypertrophy or strength block, meticulously logging progress over months, and following or customizing proven programs. Pros: deep tracking and analytics, a huge exercise database, and a strong community library of plans.
