Your muscles have data.
KYB helps you
Saudi Arabia's first EMG-based muscle assessment, built to show how your muscles perform and activate, so your training is based on your body's data, not guesswork or someone else's routine.
Most training advice
is wrong for you.
Generic fitness programs assume everyone responds the same way. EMG data proves they don't. An exercise that hammers one person's chest may barely activate yours. You can train for years and still aim at the wrong target.
Your anatomy is unique
Muscle insertion points, fibre type, leverages · they're yours. Programs that ignore them waste your time.
You can't feel activation
"Mind muscle connection" is real, but the body lies. EMG sensors don't. We measure what your muscles actually do.
Years can go to the wrong target
Without data, you optimize blind. KYB gives you a map. You walk away knowing which exercises pay off most for you.
Three steps.
One session.
Start to finish in under 24 hours from the first click. The data is yours for life.
Build
Pick the muscles you want tested. Set how many exercises per muscle (min 3 · that's the floor for honest comparison). See the live price tick down as you add more.
Test
One in-person session in Jeddah (or your city, with travel). EMG sensors map every exercise you do. We run the test, you do the reps. Bring your gym clothes.
Map for life
Walk away with your personal KYB page. Ranked best exercises per muscle, left/right asymmetry, real activation %. Updates if you ever come back.
Same lifts. Different bodies.
Different muscle activation.
Three people can do the same exercise and get three different results. KYB shows which movements actually activate your muscles best, so your program is built around your body, not someone else's advice.
Until you test, you're guessing.
Your actual data.
Not someone else's.
Every exercise we test gets ranked by your real muscle activation. You see exactly which moves hit hardest and which barely register · for your body, on the day of the test.
- · Ranked best exercises per muscle group
- · Left/right asymmetry detection
- · Sub-region breakdown (upper vs mid vs lower chest, etc.)
- · Sub-second EMG waveforms per rep
- · Bilingual report (English + Arabic)
Premium service.
Real science.
Jeddah, ready when you are
Run by Saudis, for Saudis. Home base in Jeddah; we travel to Riyadh, Dammam, and other cities for a flat add-on fee.
Performance, not diagnosis
EMG is the same technology used by Olympic teams. We measure activation, not pathology. Sign a quick waiver, get on with it.
Forever-link in your pocket
One link, mobile-friendly, installable on your home screen. Pull it up at the gym. Show your trainer. Never expires.
No subscription. No upsell.
One payment. One session. Lifetime access to the data. Want more depth later? Add another session. Same link grows with you.
The honest answers.
Built so you can decide without booking a call.
How long is a session?
Plan for 20 minutes of sensor setup per muscle plus ~5 minutes per exercise on average. Every booking starts at a 1-hour minimum even if the math is shorter. So a single muscle at 3 exercises lands at the 60-minute floor; a 3-muscle × 6-exercise build runs about 2.5 hours; a full 12-muscle deep test splits across multiple visits. The exact estimate updates live as you configure on the previous page.
What do I wear?
Normal gym kit. T-shirt and shorts work. We need skin access for the EMG sensors at the muscle being tested, so we'll briefly expose that area. Bring water and your usual training shoes.
Is it medical? Will it diagnose injuries?
No. EMG measures muscle electrical activity during exercise. We use it to rank activation and detect asymmetry, not to diagnose conditions. If something feels off, see a physiotherapist. We are not a substitute for medical advice.
Can I reschedule or cancel?
Free if you cancel more than 24 hours before your slot. Inside 24 hours, we keep 20% as a slot-hold fee · whether you cancel, reschedule, or no-show. Rescheduling within 24h doesn't reset the policy.
How do I see my data after the session?
You get a private link (kyb.best/c/yourname-xxxx). Open it on your phone, "Add to home screen" once, and it behaves like an app. No store install, no login. Forever yours.
Can I bring my trainer?
Yes. Trainers often join the session to interpret the data live with you. No extra charge.
What if I want more muscles tested later?
You book another session under the same link. The data appends to your existing KYB page; it doesn't reset.
