Seems a bit 1970s and amateurish to me.
WHat training effect are we looking for?
Are we just trying to make the training sessions hard?
This is going to make recovery from the stamina training longer and will have absolutely zero long term effect. If anything its detrimental as it eats into recovery and can lead to overtraining
A weight program to target weak muscle groups in certain players may have its place, but there's no point players doing dumbbell presses or flyes. Any short term strength gains will be minimal and quickly lost (unless we plan on doing this throughout the season)
Not impressed
