Muscle Activation Insights

The size principle explains how the body activates smaller, weaker neurons first, which can lead to a decline in fast twitch fibers if not regularly engaged. Once these fibers are underutilized, they can convert to slow twitch, limiting force production. Starting with manageable weights and focusing on efficient movement patterns can help maintain muscle health without necessarily inducing soreness, as improvement can occur without pushing to the point of discomfort.
