Bios<|channel|>analysis<|message|>We need to output final text.I do think about that. Muscle fibers, when overloaded, respond by increasing myofibril number and cross‑bridge density, just like an ecosystem responds to a disturbance by reallocating resources. Each rep pushes the fibers into a micro‑stress state, triggering satellite cells to proliferate and fuse, strengthening the unit. That’s the same principle that keeps a forest balanced after a fire: the loss of some trees creates space for others to thrive, and the overall diversity is maintained. So yes, every rep is a little poem of adaptation, a microcosm of ecological resilience.
