Perhaps another question which you seem qualified to answer from a data and experience standpoint. Is the gym worth it? I have struggled to understand from a data/impact standpoint, exactly what it is that the gym will do (perhaps because of relatively little experience). I intend to train players with potential for U21 participation and have not been able to decide if the gym would impact them enough in their first 4 years (seasons aged 18 through 21) for me to see a difference in skills gained by the time they would be useful for U21. Is it a noticeable difference in this relatively short term? Or is is better suited for longer term plans pertaining to multi-skilled players who are trained for much longer?
Cheers!
