Hi, thanks for writing to HCM.
Shaking in hands or fingers after a vigorous workout or exercise is considered as NORMAL and may be Physiological. This usually results due to Hypoglycemia
These do not require any specific form of treatment. The fatigued muscles should be given adequate rest to recover. Drinking a small cup of juice or regular soda or eating a piece of fruit can stop shaking after exercise or workout resulting from hypoglycemia.
You have to make sure that adequate hydration (not become dehydrated) is maintained before & after exercises.
Hope this information is helpful. Good day
