Introducing AI form feedback and AI-powered training coach. Flex AI is the world’s first AI personal trainer. The new update (Flex 3.0) introduces real-time AI Form Feedback and Lex—an AI persona that adapts your workout plan, analyzes your lifts, corrects your form instantly, and answers questions about training, recovery, and nutrition.
I’ve been using Flex since last year. I’ve gone back to my gym routine this year and it’s so easy for me to open up Flex and start the workout. The social media sharing with a very friendly community also gave me more confidence which I don’t normally have regarding my fitness - also loving to get inspired by other people. I can’t wait to try out more AI assistance features to help managing my workouts (which, I don’t plan very well on my own without a trainer), and correct my forms. Big thanks and kudos to Flex and the team.

This looks really solid! Having something that actually gives feedback on form could be a game changer. Congrats on the launch!
Flex AI: Your AI Personal Trainer
I’ve always loved group fitness for the daily variety, but once I went back to the gym I found myself repeating the same routine for months. That’s a big part of why I’m so excited to be part of the team building Flex AI and Lex (the AI trainer). I wanted to bring that variety back. Now I’m getting new, personalized workouts every day that fit perfectly into my routine. Using it myself has been awesome.
Flex AI: Your AI Personal Trainer
The feature I'm most excited about is the AI-enabled auto-progression -- I can just do my workouts, not having to worry about switching up my weights or reps, knowing that my set values are being optimized for every workout. Also, "Savage Lex", the AI personal trainer, is hilarious; keeps me coming back session after session.
I always get distracted in the gym in between my sets with the urge to doom scroll on my phone. I thought there was no hope for a change... until my friend told me how she was logging her workouts distraction-free in the gym with her Apple Watch.
She showed me Flex AI and I've been hooked ever since. The Apple Watch experience is the best I've found in the fitness market for a phone + distraction free workout session, and the UI is a joy to use. Sharing my workouts and progress with friends has been a fun way to keep in touch with my friends abroad too!

I genuinely love using this app myself. Not having to decide what to train each day is amazing—Lex always gives me a great plan.
As part of the Flex team, I’m really proud of what we built with the 3.0 release.
