My muscles shake during certain poses. Is it safe to keep holding them?
Yes.. to an extent. Shaking muscles during difficult yoga poses are a physiological and neurological response to working hard, and signal muscular fatigue, which is usually a good thing! Don’t shy away from a pose when your muscles start to contract and relax, but do be mindful if your alignment. If you push yourself too hard, you can increase the risk of injury. To gauge the difference, listen to your teacher’s cues and focus on your breath. If you can’t inhale and exhale smoothly, or if you start to hold or restrict your breath, your body is saying it has had enough, and your alignment could be compromised; it’s time to move out of the pose.
Another reason muscles may shake during difficult poses is dehydration, which throws off the balance of electrolytes like sodium and potassium that carry electrical impulses and allow your muscles to contract. The result: Your muscles can’t fire correctly, and they quiver. Make sure to hydrate the body!
