About
Renu is the private 1:1 coaching app for clients of Sam Thai.
Sam has coached since 2016. He built Renu for people who have trained for years and still don’t have the physique to show for it. Nothing in the app is a template. Everything is built around you and your data.
What’s inside
Your training. Block-based programming, rewritten as we go based on your real performance and recovery. Travel-week sessions for when life moves.
Your nutrition. Your targets and meal structure, built to survive work dinners, travel and weekends.
Daily and weekly check-ins. Log your numbers, photos and how the week went. Sam reviews every check-in and replies the same day.
Direct messaging. Ask Sam the in-the-moment questions, Monday to Friday.
One place for all of it. No spreadsheets, no scattered messages, no guessing what’s next.
Please note:
Renu is for current clients of Sam Thai. Access comes with your coaching, and places are limited. To apply, visit apply.coachsamthai.com
Renu provides coaching and general fitness guidance. It isn’t medical advice.
* App access requires paid coaching plan
