Let me put a warning here.
Stretching your hands to play wider chords on the piano is not without risks, especially for us who are a bit older. Overstretching can strain the tendons and ligaments in the hands, which may become less elastic over time, increasing the likelihood of discomfort or injury. Additionally, the joints in the fingers, especially those at the base, can experience stress, which is a concern for individuals with conditions such as osteoarthritis.
The muscles in the hand and forearm may also tire more quickly when holding wide stretches, potentially leading to overuse injuries like tendinitis. Repeated stretching without proper technique or adequate rest can exacerbate these issues, and older adults, who often recover more slowly from minor strains or inflammation, may find themselves more prone to chronic problems. Finally, excessive stretching could contribute to conditions such as carpal tunnel syndrome or other repetitive strain injuries, which can reduce dexterity and cause persistent discomfort.
