Why do I shake when I do planks?

Shaking muscles indicate that the move is working, which isn’t far off: According to exercise scientist Len Kravitz, PhD, of the University of New Mexico, the shaking effect is a natural effect of muscle weariness.

When your muscles are fatigued, why does your body shake instead of collapsing all at once? It has to do with your nerve cells’ and muscle fibers’ interactions. Chemical messengers that transport signals between neurons and muscle cells are depleted by difficult exercise. According to Kravitz, this causes some nerves and their accompanying fibers to stop functioning. Your body shakes like a car sputtering on a low gas tank because your cells don’t all fire at the same time – some contract while others relax.

According to Alice Holland, DPT, director of Stride Strong Physical Therapy in Portland, Oregon, exercises like planks are more prone to create tremors because your muscles must exert a lot of energy to hold your body in one place. Holding a plank, squat, or a dumbbell at the midpoint of a bicep curl — all typical barre exercises — is extremely tough because you’re fighting gravity while still keeping one position, according to Holland.

If you do these exercises on a regular basis, your body will adjust to the challenge, and your muscles will shake less as you get fitter, according to Linda S. Pescatello, PhD, a kinesiology professor at the University of Connecticut. Just be careful not to overdo it, she warns. “Muscle tremors are harmless unless you continue to do a lot of resistance exercise without taking any rest days.”

Shaking can also be caused by dehydration, according to Kravitz. “Muscular proteins contract in a fluid environment, and dehydration can cause muscle contraction signals to be disrupted,” he tells Yahoo Health. “As a result, stay hydrated when exercising.”
