Men’s Journal (2026) ranks it as one of the best free workout apps for beginners. Imagine a lifter following 5/3/1 (a percentage-based powerlifting framework built around four key lifts). They open Hevy after each session, log their sets, and within eight weeks, Hevy’s graphs show their bench press has climbed 15 lbs — visual proof that progressive overload is working. That data visibility is motivating in a way no spreadsheet can replicate. It really depends on the person using the app and how disciplined they are. If you are someone who is already very motivated to stay fit and healthy, then an app may not make much of a difference.

It offers essential customizable workout routines, tracking capabilities, and data logs tailored for weightlifting enthusiasts.
