Shaking in the legs can be caused by a variety of things. Sometimes after an intense workout the nervous system which causes your muscles to contract becomes fatigued causing your muscles to shake. Sometimes shaking is due to low levels of glucose in the muscles or electrolytes which are necessary for muscle contractions, or due to being dehydrated. If you’re experiencing shaking in your legs after workouts try increasing your fluid intake by drinking drinks that contain electrolytes and sugar in low dosages to keep your muscles hydrated and supplied with the nutrients needed to keep muscles working.
