Ever stood in the gym with someone else's program on your phone, with no idea how to pick a weight, whether today should be hard or easy, or why any of it is there?

Sunn Fitness teaches you to run your own training. Taught, not told.

Built by a kinesiologist with twelve years in clinics and gyms, hundreds of people trained, and one job the whole time: send them back to their lives without fear of the weight room.

YOU BUILD IT. SUNN EXPLAINS WHY.
Pick your level, your equipment, your days and your movements. Your program comes from your answers, with the reason behind each piece. Change anything you like. The decision stays yours.

YOU GET BETTER AT CHOOSING YOUR OWN WEIGHTS.
After each set, Sunn asks how many reps you had left (reps in reserve, or RIR) and coaches from the answer. Not "add ten pounds". A plain read on whether today calls for a little more or a little less, and why. A few weeks in, you stop needing to be told.

LOG IT IN SECONDS.
Last session's numbers sit right where you need them. Enter your weight and reps, answer one question, rest, repeat.

YOU SEE YOUR WHOLE WEEK, NOT JUST THE GYM.
Log everything you do, gym, sport, yard work, as effort times minutes. Already tracking with Apple Health? One tap brings that activity in, so nothing is missing. Your home screen is one colour: how this week compares with what your body is used to, in plain language, so you know when to push and when to pull back. The measure was developed for Olympians. We think it should work for everyone.

300+ EXERCISES, EACH ONE EXPLAINED.
What to pick up, how to hold it, when to put it down. No assumed knowledge, no gym slang. New ones filmed every week.

WHAT'S NOT HERE, ON PURPOSE.
No leaderboard. No badges. No feed. No target weight. No guilt. People who train because they understand and value it keep training. People who train from pressure quit. Sunn Fitness is built for the first kind.

A NOTE FROM ME.
I'm Robert, the kinesiologist who built this. I was the kid who found his confidence in a gym, then the trainer who watched hundreds of people find theirs. I want you to love the gym. Confidence in the gym, confidence for life.

Start with 14 days free. The gym is yours.
