Why "Teammate"
Why we call you a Teammate
Getting better is rarely a solo project. We could have said "for individuals," but that word makes training sound like something you have to carry alone.
So we say Teammate. HeartCore builds the training for your body and your goal. VERA explains the why. And a community of people chasing their own goals puts in work right beside you.
The work is yours. The journey is shared.
How it adapts
The goal doesn't change. The route does.
Bad sleep, a tweaked knee, a missed Monday, HeartCore reroutes around real life and still gets you there.
From goal to first session in 2 minutes
Say what you want
Get stronger, build muscle, drop fat, have more energy, or just feel better in your own body. Plain words are enough.
Tell us about your body
Training experience, equipment access, and any injuries or limitations. Takes 60 seconds.
Get your program
HeartCore generates a program tailored to your goal, your body, and your schedule. No planning homework.
Train and evolve
Log your sessions, rate your effort, and the system learns. Every week gets smarter.
Not another workout generator
Most apps sample exercises from a database. HeartCore reasons about the body as a connected system, grounded in exercise science, anatomy, and physiology.
Every exercise has a reason
Tap any exercise to see why it's in your session, which goal it serves, which muscles it targets, and how it connects to your progress. No black boxes, no random selections.
Your injuries are handled, not ignored
Report a sore knee and the entire session adjusts, not just one exercise. The system understands how joints and muscles are connected and modifies your program accordingly.
It learns you over time
Rate your effort after each exercise. The system calibrates to your body, learning how hard exercises actually are for you, how fast you recover, and where your strengths and limitations lie.
Recovery-aware when you want it
Connect a wearable, Whoop, Oura, Garmin, Apple Watch, Polar, Suunto, Fitbit, and more via Terra, and your sessions automatically adjust based on your recovery state. Bad night's sleep? Today's session adapts before you start.
Just talk to it
VERA sits on top of HeartCore and understands training. Ask for a quick workout, swap an exercise, check your progress, or tell it something hurts, she handles the rest with the engine's rationale attached.
