Physiotherapist Mara Tar (2024) mentioned the idea of core warm-ups as an essential component of physical preparation for musicians during an interview. The core—including the abdominal muscles, lower back, and pelvic region—plays a fundamental role in posture, stability, and breath control. A strong and engaged core helps musicians maintain proper alignment, reduce unnecessary tension, and improve endurance during long practice sessions or performances.
For these exercises, it is recommended to follow a structured routine consisting of three sets of ten repetitions for each movement, with a one-minute rest between sets. For planks, three sets can be performed, holding the position for 20 seconds to one minute, depending on individual endurance.
You will need a mat for these exercises, so you might prefer to try them at home first. However, a mat should be considered an essential "instrument" that musicians always have nearby.
