This may be a daft question but as I'm coming towards the end of the injury recovery (thank god for that) I'm in a position where I'm finally able to incorporate the concentric part of the exercise. Would it be good practice to maintain the slow negative as well as the concentric phase on a permanent basis?
From all of Coach Sommer's posts it seems to be the golden ticket, and even his videos seem to all emphasize very slow control for each movement. With this in mind is there even any point in the concentric part if it is possible to progress with harder and harder eccentric only exercises?
