Do you want to know the truth about fast-twitch muscle fiber loss and what it means for longevity? In this video, we dive into why losing fast-twitch fibers is a crucial part of aging that most longevity approaches ignore.
Some influencers claim that slow-twitch fibers can be ‘converted’ into fast-twitch fibers. But is this really possible?
I’ll break down the facts, including why this fiber loss is largely irreversible and how it impacts the body’s ability to stay strong and agile with age. Plus, I’ll briefly cover which types of exercises can help you maintain the power of the remaining fast-twitch fibers you still have.
