max lenght of a training session?

What is an optimal result?? Workouts blend into each other, so you have the sprint, then weights, then… etc. So the question now becomes, is it better to maximise weights after speed, or is it better to go with the “full glass” theory, which is that you do the weights that are possible based on what has already been done on the track? This goes back to the basic question of how strength is achieved. Do weights make you better on the track or do high quality track sessions improve your lifts and those lifts set up a stimulus that benefits the next track session?.
If you can, get the weights lecture series from the site store to get the full picture.
