I forget where I heard it first, but I think it was some reputable (otherwise I would have ignored it) German literature which suggested that all athletic S&C programs should be 70:20:10 Concentric:Eccentric:Isometric.
I think it’s a very interesting concept and there is a place for Eccentrics and Isometrics in some cases – but again it all has to be fitted into a general program.
I’m not sure if I agree that eccentrics necessarily give the most hypertrophy Tom – but perhaps you mean that increasing eccentric component and therefore TUT is useful?
