One of the problems with eccentrics is being able to set them up easily.

Many people are limited by how much than can lift (concentric) to be able to get a heavy load that they can lower (eccentric).

If you can figure out how to get around this, you might make more gains in your strengthening and performance.

“The inclusion of eccentric loads not constrained by concentric strength appears to be superior to traditional resistance training in improving variables associated with strength, power and speed performance.”
