Si has pasado por una lesión de rodilla y aún no puedes volver a tu deporte favorito o simplemente llevar el día a día sin limitaciones por dolor constante, falta confianza, pérdida de fuerza y estabilidad o miedo a recaer... te presento mi programa de readaptación online MyRehab. MyRehab es un programa de entrenamiento online que te va a ayudar a recuperarte de tu lesión o dolor de rodilla, a aprender a entrenar de forma saludable sin tener que pasar mucho tiempo en el gym, a volver a hacer el deporte que más te guste sin dolor y a prevenir recaídas una vez que vuelvas al hacerlo con una rodilla más funcional que antes de la lesión. Con MyRehab podrás entrenar con motivación sabiendo que esta es la solución a tu lesión. ¿Para quién es? - Este es un programa enfocado en ayudar a personas que tienen una lesión o dolor de rodilla y quieren volver a disfrutar de su deporte sin dolor y minimizando al máximo el riesgo de recaídas. ¿En qué consiste? - Antes de comenzar con el trabajo, será necesario realizar una entrevista donde poder conocer más sobre ti, tus objetivos, evaluar tus necesidades y punto de partida. Después, haremos una sesión de valoración funcional donde comprobar tus niveles de fuerza y movilidad para proceder con el plan de actuación. - El sistema de trabajo 100% individualizado busca una rodilla funcional mediante trabajo de fuerza, movilidad, propiocepción y estabilidad adaptado en todo momento y aplicando intensidad de forma progresiva en cada fase de trabajo buscando que la rodilla no solamente vuelva a ser la de antes de la lesión sino incluso mejor. - A diferencia de la mayoría de programas, se basa en hacer un trabajo funcional y adaptado a tu caso particular, para que puedas lograr llevar el día a día sin limitaciones sin tener que abandonar pensando que tu caso no tiene solución. - El objetivo con MyRehab es que logres los mejores resultados de tu vida y que, además, puedas mantenerlos para siempre. ¡Únete ya al equipo MyPerform!

About

Resonance

This app personalizes breathing exercises by identifying your unique resonance frequency, which optimizes heart rate variability. It uses live biofeedback from your existing wearable devices to train you at your ideal pace for improved coherence and well-being. Practice sessions can be done offline without a sensor after initial setup.

Highlights
  • Personalized resonance frequency identification
  • Live HRV biofeedback
  • Works with existing wearables (Garmin, Polar, Fitbit)
  • 12-minute frequency assessment
  • Offline practice sessions
  • Session Quality Score tracking
  • Heart rate and HRV trend charts

Most breathing apps give you someone else's breathing rate. Resonance: HRV Biofeedback finds yours. Your resonance frequency — the breathing pace that maximizes your heart rate variability (HRV) — is unique to you. It's usually 4.5 to 6.5 breaths per minute, but the exact rate is personal. Breathing there maximizes respiratory sinus arrhythmia (RSA) — the natural rise and fall of your heart rate with each breath. A generic pace like "6 breaths per minute" misses it for most people. Resonance uses live HRV biofeedback to measure your actual resonance frequency, then trains you at that exact pace. START WITH THE WATCH YOU ALREADY OWN Turn on heart-rate broadcast on your Garmin, Polar, Samsung, or Fitbit watch and you're ready — no extra hardware to buy. Any Bluetooth chest strap or arm band works too (Polar H10, Garmin HRM-Pro, Wahoo TICKR, and more). You only need a sensor twice: for the 12-minute assessment that finds your frequency, and whenever you want live coherence biofeedback. Every daily practice session after that runs at your stored pace with no sensor at all. FIND YOUR FREQUENCY IN ABOUT 12 MINUTES A three-phase protocol — ASSESS, REFINE, HOLD — scores candidate breathing rates against your live HRV using the published Shaffer & Meehan (2020) six-criteria coherence model, then locks in your personal resonance frequency and refines it each session. LIVE HRV BIOFEEDBACK, NOT A BLACK BOX • Real-time heart-rate trace and frequency spectrum during every session • All six Shaffer coherence criteria live — peak LF power, single-peak dominance, LF concentration, peak height, SDNN, RMSSD • Watch your heart rate turn into a smooth, sine-like wave as heart coherence builds TRACK REAL IMPROVEMENT • Session Quality Score (0–100) after every session — time in coherence, RSA amplitude, and consistency, scored separately • Full session history with HRV trend charts for coherence, resonance, RMSSD, breathing pace, and heart rate • Shareable session cards with your actual heart-rate trace BUILT FOR DAILY PRACTICE • A calm breath pacer with visual, audio, and haptic cues for eyes-closed sessions • 10 sound packs and a breathing exercises library with multiple session modes • Custom inhale/exhale ratio and practice reminders PRIVATE BY DESIGN Your heart-rate data never leaves your device. No account, no cloud, no sign-up. Everything works offline. FREE TO START The full resonance assessment and unlimited practice are free. Resonance Pro adds the adaptive pacer, full breath history, the complete resonance score, sound packs, and the exercises library — available monthly, annually, or as a one-time lifetime purchase. THE SCIENCE Built on 30+ years of peer-reviewed HRV biofeedback research. The engine uses Lomb-Scargle spectral analysis, the HeartMath coherence ratio, and the full Shaffer six-criteria model, all computed on-device. Resonance: HRV Biofeedback is a wellness and breathing-training tool, not a medical device. It does not diagnose, treat, or prevent any condition; supported heart-rate sensors are consumer fitness devices, not medical hardware. Always seek a doctor's advice in addition to using this app, and before making any medical decisions. References: Task Force (1996) Lehrer et al. (2000) Shaffer & Ginsberg (2017) Shaffer & Meehan (2020) COMPATIBLE DEVICES Any consumer Bluetooth 4.0+ heart-rate sensor using the standard Heart Rate Service — smartwatches, chest straps, and arm bands. WHO IT'S FOR Anyone training heart coherence and resonance frequency breathing as a daily practice. First-timers who want a guided daily practice that works, athletes using breathwork to recover and downregulate, and researchers who want live spectral analysis, RMSSD, SDNN, and raw R-R export. No prior HRV knowledge needed. Resonance frequency breathing. HRV biofeedback. Measured, not guessed.

Verdict

The call

The clearest difference is in-app purchases: MyPerform at none against Resonance's 3. Resonance's advantage is update cadence (weekly vs every 7 months). On price, ads, device support and iOS requirement there is nothing between them.
