I don't know much about nutrition in regards to eating after a bjj workout. But after last training day I felt weak and a little light headed. So this time I made sure to drink more water throughout the day and to bring an apple with me to eat after I was done training. In my opinion it made a difference. As soon as I was done the class / training I ate it. I felt WAY better soon after.
Now don't get me wrong I still drink the protein while driving home to eat. But I feel the apple was a nice quick healthy way to recover. Could it be the natural fibers and sugar? Or is it just a placebo effect? Or do I simply need better cardio?
