Fuerza dos veces por semana: un paso, beneficios para todo

4 minutos de lectura

Si de todos los consejos un hombre de más de 40 pudiera elegir solo uno, sería el entrenamiento de fuerza. Actúa a la vez sobre el metabolismo, el corazón, los músculos, los huesos, el ánimo y el deseo. Y no hace falta un gimnasio.

Por qué funciona

Con honestidad: el entrenamiento de fuerza no sube la testosterona en reposo. Entrena por la fuerza y el metabolismo, no por un «subidón» de la hormona.

Cómo hacerlo

Con un entrenador, el resultado y la seguridad son mayores. En VIA-L hay un «Entrenamiento del día» guiado por voz: puedes empezar por ahí.

Quién debe tener más cuidado

Si no estás seguro de que la carga sea adecuada para ti, coméntalo con el médico. Si notas dolor en el pecho, falta de aire o mareo durante el esfuerzo, para y ve al médico enseguida.

Qué puede estorbar

Qué esperar

El ánimo y la energía suelen cambiar antes que los músculos y la cintura. Registra los entrenamientos y cómo te sientes en VIA-L: en unas semanas verás qué cambia en ti.
