Shüren (antes SerFit) es la app de tu entrenador personal: tu plan de entrenamiento, tu dieta con recetas y tu seguimiento semanal, en un solo sitio y siempre al día. Es la app para los atletas de los entrenadores que trabajan con Shüren. Para entrar necesitas la invitación de tu entrenador; si aún no tienes uno, en shurenapp.es encontrarás cómo empezar. ENTRENAMIENTO PERSONALIZADO Tu rutina, diseñada a tu medida y actualizada cada semana con sobrecarga progresiva. Registra series, repeticiones y pesos; cronómetro de descanso que te dice qué toca después; récords personales al instante; y si dejas un entreno a medias, la app te devuelve al ejercicio exacto en el que estabas. CORRE CON SHÜREN Graba tus carreras con el GPS del móvil: distancia, ritmo, parciales y el recorrido en el mapa. Con la pantalla bloqueada sigue grabando, y ves el tiempo, la distancia y el ritmo en la pantalla de bloqueo. También puedes importar las carreras de tu reloj. NUTRICIÓN CON RECETAS Y SUSTITUCIONES Tu plan de comidas con calorías y macros claros. Casi 1.500 recetas con ingredientes y preparación. Si no tienes un alimento, la app te propone con qué cambiarlo —también por la marca de tu supermercado— con la cantidad ya calculada para que tus calorías y macros no se muevan. Lista de la compra automática cada semana. ESCÁNER DE COMIDAS Y PRODUCTOS Haz una foto a tu plato y obtén sus calorías y macronutrientes, o escanea el código de barras de un producto para ver su información nutricional.
