So leaving the box last night, I am slowly walking to my vehicle and open the door to get in....and bam Charlie horse in my calf. I then clenched my hand around my keys and got a cramp in my hand. Forced myself back out of the car and walked around and stretched. Hurt so bad. I got through the workout to only hurt badly after. Today's workout is extreme and I am not looking forward to it. First time deadlifts. I hurt so bad but I will be there.
