What's holding you back in bed?
During sex, you usually last…
When you're turned on, your erection is…
Before sex, you feel nervous…
Your #1 lever: control
Your Duro plan starts with control kegels (slow and quick squeezes) and a breathing technique to slow your arousal down.
Your #1 lever: firmness
Your Duro plan focuses on long pelvic floor holds and hip strength, which help keep blood in your erection.
Your #1 lever: your head
Your Duro plan mixes breathing, short exercises and coaching to take the pressure off before and during sex.
General guidance, not a diagnosis. If you have pain or a problem that won't go away, talk to a doctor.

The control muscle
The muscle your gym skips.
Your pelvic floor is involved in ejaculation and helps keep blood in your erection. Like any muscle, you can train it. Try it now. It takes 30 seconds.
Squeeze like you're stopping your pee midstream. Keep your butt, abs and thighs relaxed.

Built on pelvic floor training, not hype.
Pelvic floor exercises are among the methods urologists and physical therapists study for premature ejaculation and erection problems. Duro makes them simple, guided and daily.
Premature ejaculation
In a 2014 study, 33 of 40 men gained control after 12 weeks of pelvic floor training.
Pastore et al., 2014Erections
In a randomized trial, after 6 months of pelvic floor exercises, 40% of men got back normal erections and 35.5% improved.
Dorey et al., BJU Int, 2005Breathing
In a review of 15 studies, slow breathing (under 10 breaths a minute) lowered anxiety and increased relaxation.

FAQ
Does it actually help you last longer?
Pelvic floor exercises showed encouraging results in several small studies on premature ejaculation, but every man is different and nothing is guaranteed. Duro itself hasn't been tested in a clinical trial. What matters is consistency, and Duro is built so you can stick to 5 minutes a day.
How long until I notice a difference?
In studies, programs usually run 8 to 12 weeks. Daily practice matters more than intensity.
What is a kegel exercise for men?
A voluntary squeeze of your pelvic floor, the muscle you use to stop peeing and to hold back ejaculation. Squeeze, hold, release. Duro shows you how to find it and guides every rep.
Does it help with erections too?
Your pelvic floor helps keep blood in your penis during an erection. Studies show improvement in some men with mild to moderate erection problems. If it happens often, see a doctor too: erection problems can be an early sign of heart disease.
Is it discreet?
Yes. No account or email, the screen is hidden in the app switcher, and nobody can see you doing the exercises, even sitting at your desk.
How much does it cost?
The 3-minute check-in is free. To follow the full program, Duro offers a subscription billed through Apple, with the price shown on the App Store before you pay. Cancel anytime in your iPhone Settings, under your name › Subscriptions.
Does Duro replace a doctor or medication?
No. Duro is a training program, not a medical device. If you have pain, blood in your semen, a sudden problem or any doubt, see a doctor or a urologist.
Is it on Android?
Not yet. Duro launches on iPhone first (it's in Apple's review right now). Leave your email via "On Android? Get notified" and we'll tell you if an Android version comes out.
Is the app in English?
No. For now, Duro is in French only: menus, voice guidance and coach Victor. The 3D model and timers show you every squeeze and every move, so you can still follow along.
