What is the most effective way to train for 400m when you can only train 3 days a week? All the training programs I read are based on training 6 days a week. My job does not allow me to train this often, but obviously I want to get the most out of my training. I am a female quarter miler with pb's of 26.2 for the 200m and 59.0 for the 400m.
