Does your body shake during a workout due to that muscle group not being actively maintained or because of something else? And how do you minimize or eliminate the shaking?
The shaking is a good sign that you are working your muscles. I wouldn't worry about it, my coach actually calls it a good thing! However, if you push yourself too hard too often, you may develop an injury. The shaking will go away as your muscles continue to strengthen.
That shaking is muscle fatigue, after a while that's what you should be working out untill. However do not push yourself for too long because a while after muscle fatigue obviously your muscle womt be fatigued but asleep if you know what I mean (literally they will stop)
But you have to be an idiot to push yourself to that point.
