Some revealed that pushing by way of shaking left them with torn ligaments. Others weren’t so certain.
“The feedback in that TikTok have been so utterly polarized,” Myers says. “So many individuals stated, This makes a lot sense, thanks a lot for saying this. After which all the remainder of the feedback have been like, You are unsuitable. The shaking means it is working, the ache means it is working.”

Why your muscle tissue shake throughout a exercise
Muscle shaking throughout train can have two potential causes, in response to Matthew Accetta, an train physiologist on the Hospital for Particular Surgical procedure. First, your muscle tissue is likely to be drained. Or they is likely to be attempting to do one thing they’re not used to, like a brand new motion or lifting a heavier weight. In each instances, shaking is an indication that your nervous system is attempting to recruit extra muscle fibers to get the job carried out.
“As muscle fibers grow to be fatigued throughout train, your physique must stimulate extra muscle fibers, which require extra motor neurons to fireplace,” Accetta says. “The impulses that journey by way of the nervous system and to the neuromuscular junctions to hold out exercise are what trigger the muscle tissue to twitch and shake.”
In the event you’re attempting out a brand new transfer, you would possibly anticipate shaking. “When the physique experiences a brand new stimulus, it’d require new muscle fibers and neuromuscular junctions to activate,” Accetta says. “As these fibers and junctions activate for the primary couple of occasions, they could twitch and shake till they grow to be accustomed to the stimulus.”
This physiological rationalization is what knowledgeable Myers’ TikTok recommendation.
“Your physique’s sending you a sign that the muscle is fatiguing,” Myers says. She provides that you simply would possibly begin shaking should you’re not participating the correct muscle tissue, so your physique is attempting to compensate by activating different muscle tissue, which may trigger the shaking and even potential cramping.
Must you cease doing an train in case your muscle tissue begin shaking throughout a exercise?
Shaking will not be one thing that you must ignore, but it surely doesn’t essentially imply it is advisable to completely give up your exercise, both. One of the best ways to know this sign is to consider shaking like a “yellow mild,” in response to Accetta.
“Muscle shaking throughout train must be seen as an indication to decelerate and be able to take a break, form of like a yellow site visitors mild,” Accetta says.
Myers agrees that the yellow mild analogy is “the proper strategy to put it.” She says, “It is saying do not go any additional than the place you might be proper now.”
The issues (and accidents) occur when folks pace up and run the pink mild.
“In the event you push by way of the yellow mild, you may ‘crash’ and damage your self,” Acetta says. “The pink mild is full and whole exhaustion and fatigue. We would like to have the ability to catch ourselves and decelerate earlier than we blow by way of that pink mild. [Shaking] will not be an indication to utterly cease what we’re doing, however must be seen as an indication to organize and prepare to cease.”
What occurs should you hold going after your muscle tissue begin shaking throughout a exercise?
The implications of blowing by way of the yellow could be each psychological and bodily. “If we proceed to train whereas we shake, we are able to trigger extra pressure and harm to our muscle fibers or extended soreness,” Accetta says. “The surplus pressure and muscle fiber harm can result in joint sprains and muscle strains if there isn’t a correct restoration time between workout routines or reps.”
That extended soreness would possibly flip you off from exercising extra: In the event you’re giving it greater than you must at the moment, you is likely to be hesitant to get again to the barre, gymnasium, or reformer tomorrow.
What to do when your muscle tissue begin shaking
So how ought to we put that yellow mild analogy into motion? On the level when your muscle tissue begin shaking, you would possibly wish to change up your kind to one thing much less taxing. For instance, should you’re shaking in a plié together with your heels lifted, contemplate dropping the heels, or rising up a bit larger so your knees aren’t bending fairly as deep. Acknowledge that you simply most likely solely have a number of extra reps in you, after which give your self a relaxation.
“There have been so many feedback [on TikTok] saying, I pushed by way of the shaking after which I could not stroll for 2 days, or my instructor inspired me to push by way of the shaking and I finally tore a muscle,” Myers says. “We predict now we have to only hold pushing by way of it as a result of it signifies that it is working. However that is your physique telling you that it is advisable to pull it again.”
