Thoughts on Charlie Francis and soccer

Yes, the example with overtraining was not the most appropriate, sorry. But you can choose whatever physiological trait you want.
Technology, as I see that, as I am not so “clinically” oriented, can be very useful in terms of first principles that directly or indirectly can affect a training session (can be a training itself). But I’m not thinking about something to be plugged exclusively. But now I more clearly understand your point, thanks.
