Very Easy to Use/Follow

The app is visually appealing and makes everything extremely easy and concise to follow. As a Division One Athlete, having this right at the tip of my fingertips and can constantly track my own gains and progression by myself, it adds a whole new level of accountability and sense of accomplishment. I also really like the AI Coach feature. Something new and clearly using AI to benefit me is a win.

GREAT APP!

As a retired college athlete, I’ve found it hard to create workouts that help me work towards my personal fitness goals. Now, Flex has helped me create proper workouts and a great training routine. I highly recommend to anyone looking for a way to track their workouts and to see real results.
