For example…
In a study from researchers at The Journal of Strength and Conditioning measured the effects of isometric holds on vertical jump.
They found that performing isometric holds created significant increases in vertical jump, compared to those who didn’t do the isometric holds.
In less words, isometric holds increased the subjects all around explosiveness - significantly.
In another study from Spain, researchers studied the effects of isometric holds on team sport athletes…
The findings?
They saw vertical jump soar, speed increase, and agility shoot up by nearly 15%...
Which is pretty astounding.
And as far as building muscle goes…
Study after study, and field-test after field-test, has shown that isometric holds contribute to strength and muscle…
Because it increases muscle activation and fiber recruitment.
And when you’re stimulating more muscle fibers…
You’re able to build more muscle.
