3 Day Slump

I've decided the third day going to the gym in a week is the worst. Especially on a night like tonight, where the gym was less crowded. No one's there, the energy is low, I'm exhausted and my back is killing me. I push through however many rounds on the bags and mitts in what feels like 100 degree heat. Day 3 sucks BIG TIME. I quit you, day three.
