I was up all night redoing an erased homework assignment, but still felt energetic enough to do some early-morning bag rounds. The issue here is muscle catabolism, not fatigue. One night should not have any drastic consequences, but I lose weight too easily to not be wary. Consistent eating throughout the night/morning and vitamin supplementation should have stifled this.
I've also discovered a simple enhancement to improve my standing bag. Propping it up close to the heavy bag causes it to hit and bounce back much faster and more unpredictably at me.
