LAST LONGER. TAKE CONTROL OF WHEN YOU FINISH. 5 MINUTES A DAY. Stop hoping you'll last longer. Train for it. Slowr turns pelvic-floor training into a simple daily system built for one goal: more control in bed. Guided Kegel and reverse Kegel training. Progressive workouts. Measurable progress. Practical techniques for when it counts. 5 minutes a day. Train the muscle involved in ejaculatory control. PROVEN TO HELP MEN LAST 4× LONGER Slowr is built on published clinical research into pelvic-floor rehabilitation for men with lifelong premature ejaculation. In one 12-week clinical study, the results were striking: 4×+ LONGER IN BED. Men increased their average lasting time by more than fourfold. 82% GAINED CONTROL. 33 out of 40 men gained control of their ejaculation reflex after pelvic-floor rehabilitation. Slowr turns the principles behind that research into guided workouts you can follow from your phone. The science works. Now do the work. TRAIN THE MUSCLE. CHANGE THE OUTCOME. Your pelvic floor plays a key role in ejaculation. Train it to become stronger, more coordinated, and more responsive. Slowr guides every workout: Squeeze. Hold. Rest. Repeat. The timer handles every rep and set. No counting. No guessing. Five minutes. Done. KEGELS ARE ONLY HALF THE SYSTEM Lasting longer isn't just about squeezing harder. You need to know when to contract — and when to relax. Slowr trains both: Kegels — build strength and contraction control. Reverse Kegels — release tension and develop relaxation control. Slowr adds breathing and practical techniques for using that control when it matters. Don't just strengthen the muscle. Learn to control it. 5 MINUTES A DAY. REAL CONTROL IN BED. No hour-long routines. No equipment. No complicated program. Open Slowr. Follow the timer. Train for five minutes. Get on with your day. Workouts progress as you move through the program, giving you a clear path from beginner to advanced control. WATCH YOUR STAMINA CLIMB Log how long you last and watch the numbers change. Track your first, latest, and best durations. Watch your graph climb. Build your streak. See your level rise. Turn something unpredictable into something you can train, track, and improve. 100 LEVELS. ONE GOAL: CONTROL. Every workout earns points. Every point moves you forward. Slowr turns pelvic-floor training into 100 levels of progression. Start where you are. Train. Level up. Keep climbing toward control. KNOW WHAT TO DO IN BED Training is only half the equation. You also need to know how to use what you've built. Slowr teaches: How to Kegel — find and train the right muscle. Reverse Kegels — release unnecessary tension. Breathing — stay relaxed and controlled. In Bed — apply the techniques when it counts. The Science — understand why the training works. No more guessing. Know what to do when it matters. BUILT FOR MEN WHO WANT TO LAST LONGER Slowr isn't a generic pelvic-floor exercise app. It's built around one mission: Better ejaculatory control. Everything—from workouts and progression to tracking and lessons—is designed around that goal. - Guided daily pelvic-floor workouts - Kegel + reverse Kegel training - 100 progressive levels - Guided timer with haptic and audio cues - Duration and progress tracking - First, latest, and best duration metrics - Streaks, points, and level progression - Breathing and relaxation techniques - Techniques to use in bed - Step-by-step instruction - Research behind the training STOP HOPING.
