OLM is the training companion for martial artists who take their progress seriously — one place for your journal, your belt path, and your technique library, whether your gym runs on OLM or you train on your own. YOUR TRAINING, REMEMBERED Every class you log builds a picture of your game. Tag what you worked on, or just talk it through — OLM's AI pulls out the positions and techniques and maps your focus over time. NEW: A LOG THAT ORGANIZES ITSELF Your training now groups by the week, so it never piles up. See a calendar of the days you trained, clear a whole week in a tap, or recap your week out loud and let AI handle the rest. Flip your focus breakdown between the numbers and a chart with a single tap. YOUR BELT, YOUR HISTORY — EVERYWHERE Your rank and training history belong to you, not one gym. Switch academies and your journal, your promotions, and your progress come with you — tracked per discipline, so a judo black belt starting jiu-jitsu keeps both ranks. A LIBRARY THAT TRAINS WITH YOU Explore positions and techniques, follow the systems of the greats, and build game plans you can study between sessions. TRAIN ANYWHERE Member of an OLM gym? Check in, see your classes, and keep waivers and billing in one place. No gym on OLM yet? Log your own open-mat and solo sessions the same way — nothing about your progress waits on a membership. BUILT FOR EVERY MAT Brazilian jiu-jitsu, judo, muay thai, boxing, kickboxing, wrestling, MMA, and more. Train. Log. Remember. trainolm.com
