The other day I had a great conversation with a female client of mine about training. She is an avid runner and is regularly in the gym five to six days per week. She admits that her frequent training is for managing the stress of her busy life, but also fear. She fears that if she doesn't keep her training frequency up, she will surely lose strength and gain body fat. However, I had to explain to her, that she also was hurting her body. Physically she was suffering chronic injuries, and psychologically she was suffering fear, anxiety, and a lack of self confidence. I tried to explain to her that there was an optimal training stimulus to improve her strength and fitness, and she was beyond that. After all, exercise training is a stress and your body has to be able to recover from that stress. If not, you are not improving your fitness or health (but your weight on the scale may stay down).
