KLINCH is a drilling tool for Muay Thai, Kickboxing, and MMA. You build the combinations you're working on, then drill them against audio cues until they stop requiring thought. BUILD YOUR COMBOS Assemble any combination from punches, kicks, knees, elbows and teeps — plus the defensive movement that belongs between them: slips, checks, parries, catches. THREE WAYS TO DRILL Coach calls each strike out loud, then gives you rest beats to reset your stance before the next rep. Cadence lets you compose the rhythm yourself — bursts, syncopation, pauses — and calls it back exactly as you built it. Pulse is a clean metronome: one strike per beat, at whatever tempo you set. PROGRESS THAT TAKES TIME Every rep counts toward a mastery stage: Fresh, Drilling, Honing, Grooved, and finally KLINCH'D at 1,000 reps. The stages are tuned to take weeks, because that is how long technique actually takes to set. FILM ROOM Record a session and review it afterwards, frame by frame. TRAIN WITH YOUR GYM Coaches can assign combos, broadcast class plans, and see what their students are drilling between sessions. KLINCH ALPHA PRO Free includes 8 combos, 5 guided sessions a week, one saved recording, and 30 days of stats. Alpha Pro removes every limit: unlimited combos, unlimited Coach and Cadence, every recording kept, and your complete training history. $7.99 per month or $49.99 per year.
