So I've been a twig all my life, and along with being super skinny I've been plagued with extremely low energy and shaking. I'll give you a couple of examples.
I've been enrolled in Jiu Jitsu for just about 3 years now, just about every session I would spar for the first time and after 3-5 minutes I would be uncontrollably shaking and just dead tired. Every competition I went too I was only good for one match, then the next one I only had enough energy to postpone my defeat for a minute or two by being passive.
About two weeks ago I took it upon myself to start utilizing the bench press in my shed and start some weight training. Most of the time I've been lifting, I would do a set of 10 reps of bench pressing rest a min, a set of 15 curls rest a min, a set of 10 shoulder presses rest min, then when I go back to benching my arms are just start unbelievably shaking and my energy is absolutely 0. It feels like my muscles aren't broken down much I feel no burn but I have no energy to keep benching.
I've been taking multivitamins, vitamin D, L-arginine, omega-3 for months. Just recently started using some True-Mass protein and started juicing fruits/vegetables everyday.. Have been eating chicken breasts every day, Drinking loads of water. The only thing I think I might be lacking in is calories.
I would like some opinions of experts or other users who may have had some experiences like mine and what they have done to help them overcome it. I want to get stronger, I want to get faster, I want to get bigger, but I have a barrier and would like some advice.
