Log every wrestling match, BJJ roll, boxing round, MMA session, and tournament result. Earn XP. Share your wins, post to the feed, and climb the global leaderboard. Build streaks that outlast your worst weeks. Renshi is the workout-and-competition tracker built for combat-sports athletes who actually compete.
TRACK EVERY ROUND
Quick-log any session in under 10 seconds. Drilling, live rounds, sparring, strength, conditioning, mobility, film study — every minute on the mat counts.
LEVEL UP YOUR GAME
Earn XP for every workout. Climb from Rookie to Mythic across 15 rank tiers. Build your OVR — a single number that captures how seriously you're training right now.
BUILD A FIGHT CAMP
Plan an 8-, 10-, or 12-week camp with built-in loading and taper phases. Hit your daily targets to earn camp XP and unlock camp-specific badges.
LOG COMPETITIONS
Track every tournament, fight, and match. Wins, losses, submissions, decisions — all of it. Your competition record becomes part of your fighter profile and earns its own XP, badges, and share cards.
POST TO THE FEED
Share your sessions, camp finishes, and competition results to the Renshi feed. Every share card bakes in your XP, streak, and overall stats — so your wins post themselves. Follow other athletes who train as hard as you do.
CLIMB THE LEADERBOARD
Compete against every other athlete on Renshi. Weekly and monthly champion badges go to the athletes who put in the most work.
FOLLOW YOUR TEAM
Join or create a team. See your teammates' feeds. Compete on the team leaderboard. Train together, climb together.
EARN BADGES + ACHIEVEMENTS
Dozens of badges and achievements to unlock — from "Early Bird" (train before 6 AM) to "Iron Will" (100-day streak) to "World Champion" (#1 on the global leaderboard).
