I do not believe there is any specific exercises for “chaos training”
for the scrum, as I do not think there are any rugby specific exercises
as much as some position and head coaches would like there to be, get
them strong and powerful, fast and aerobically/anaerobically conditioned
and let the coach give them the skills and the tactics, although I do
love the Zercher lift and squat and the combo good morning movements for
my front 3, cheers, ashley
