I wanted to ask you guys if you always train when youare in perfect conditions, or still workout when you have a headacheor feel like really exhausted? Sometimes I have really bad headaches,so it is hard for me to motivate myself to train, and I don't know ifI should force myself, or not. Also, there are nights when I have towork a lot, and the next day I feel broke, so it is also hard to getmotivated for training – should I force myself?
