It seems it is not about just creating joint actions/rotory torque.
It's also about; squeezing, twisting, holding, cramping etc.
Going by this-angles do matter as does varying ROM.
Work your muscles not your joints.
"The predominant thinking of the last 50 years is that 100 percent of the muscle force comes from changes as muscles shorten and myosin and actin filaments overlap. But when we isolated the effects of filament overlap we only got about half the change in force that physiologists know muscles are capable of producing," Williams said.
The rest of the force, he said, should be credited to the lattice work of filaments as it expands outward in bulging muscle -- whether in a body builder's buff biceps or the calves of a sinewy marathon runner.
"One of the major discoveries that David Williams brought to light is that force is generated in multiple directions, not just along the long axis of muscle as everyone thinks, but also in the radial direction," said Thomas Daniel, UW professor of biology and co-author on the paper.
