This past Thursday morning I awakened with a pounding headache. I debated for a moment about staying home from the gym, but decided against knowing I couldn't go after work. So off I went after eating a waffle w/ peanut butter and a glass of water.
I jumped on the treadmill aiming for about 20 minutes of a run/walk interval. It was difficult because with every run interval I could feel the pounding of my headache. However, by the time my 20 minutes were up the headache was gone! That was an awesome feeling! I'm so glad I forced myself to go and get my workout in. It was SO worth it!
