Dr. Yessis wrote: -- All exercises are dynamic. Isometrics is never
for max strength of any body part.

[Telle writes: I can see the reason for isometrics for those body parts that 
remain
stable during exercise though I would still tend to believe that loading the
trunk inertially would be more effective than statically]

[Telle writes: -- At the isometric phase of an E-I-C (eccentric-isometric- 
concentric)
dynamic lift wouldn't all “parts” be stabilized? Isometric forces are quite
a bit greater as a function of eccentric history. I'm thinking a static
isometric effort is non specific to dynamic E-I-C actions?]
