I remember that there are different types (sizes) of muscle fibers, and they are activated according to the force required. For example, if we have to lift 50lb weight, large muscle fibers will be activated whereas if small muscle fibers will be activated with less force (like resistance band).

And, I am curious as to what type of roles these different muscle fibers play role in our body. Perhaps, working on these smaller muscle fibers is more crucial in improving balance than on large muscle fibers?
