On a recent flight, model and cookbook author Chrissy Teigen (August 23, 2019) shared a series of videos while stretching her legs on Instagram stories. The dim lighting made it clear why she posted them: her legs shook uncontrollably when she raised one leg to stretch it, and the same shaking occurred again when she switched legs.
"Just a normal stretch," Chrissy said in the video, seemingly unfazed by the unusual occurrence. However, the question remains: is this normal? The shaking could be caused by the long haul flight or her previous over-the-top clapback, but there might be a more probable explanation.
When you stretch a muscle, the myotatic reflex, or stretch reflex, kicks in, causing the muscles to involuntarily contract, or shake. This phenomenon has been explained by Science Direct.
This is not the first time Chrissy has experienced unexplained muscle twitching. Earlier this summer, she shared a video of her arm twitching, which showed a close-up view of her arm twitching along with visible cupping marks. She has also suffered from hives on her thigh and butt.
