The Living Force
Thanks for mentioning this Gaby. Sometime after starting the iodine protocol I started shaking when doing EE or any sort of meditation where I focus on being present to what's going on in the body. Shaking is one of the ways that the body de-stresses and releases hyperarousal energies cause by some sort of trauma, as explained by Levine. After experimenting with HIIT I noticed the same thing; slow, high intensity exercise seems to be helping the nervous system to reset. I already feel better after only two sessions of HIIT, I wonder what will happen if I keep at it.
To be clear, are you shaking through the entirety of the movement or are you experiencing a brief bout of shaking a little after completing the exercise? In the context of weight training jerking isn't exactly the goal and if it happens you should either back down on the weight a bit or move slightly faster. It can actually be dangerous to constantly shake while under load fwiw.
