Another injury

Got in two exercises. During the 60# single dumbell row, I felt a pop by my right bicep. It had been sore for a long time. Afterwards, the bicep had an odd shape, like it pulled away from the attached tissue. It hurts to pickup anything heavier then a coffee cup. I will be off till at least the first of the year, depending on how it feels, and heals. Gives me time to catch up with my running which I have gotten behind on. I will be starting second shift next week at work, so I will be able to get more time in at the gym
