Booth Health Tuesday is back after Hurricane Ida strolled through my area. Her winds were fast but her forward movement was slow.
Muscles of the skeleton are made of fast twitch and slow twitch fibers. Slow twitch fibers make up a large part of deep and core muscles responsible for posture and stabilization, while fast twitch fibers are for movement and bursts of activity.
Slow twitch fibers can work under heavy loads (posture) for a long time while fast twitch fibers are fatigued more quickly (movement).
Poor posture can cause core muscles to weaken from lack of use. Improper posture calls on fast twitch muscles to do the job, and these muscles become tired, fatigued, and achy.
Quick tip: Add a mirror to your studio/work area and let it be a reminder to lift yourself to better posture.
