Most of the jiu jitsu sessions are usually pretty tough but I find I generally find them less so after a while. Lately I have been gassing way too quickly both in sparring and warm ups. I am not sure if it is due to over training (I have been training more recently) but I don't have the other signs of over training that have happened to me in the past. When I over trained in the past the following things would happen 1) Unmotivated to train. 2) Unable to concentrate. 3) Lethargic 4) Decrease in weight None of those things have been happening to me so I don't understand why I am gassing faster than usual. Anyone had a similar problem and how did you overcome it?
