Our take on Eccentric Hooks, also known as Weight Releasers
Sold as a pair.
Adjustable from ~19 inches to 36 inches, in 1-inch increments. (for taller individuals, squat extensions are available for purchase and allow an additional range of 37 to 51 inches)
Can be used on various lifts including bench press and squats.
Great for overloading the eccentric/negative portion of the lift.
Weight is stacked on each releaser and set on each end of the barbell. At the bottom of the lift, the releasers kick off of the barbell and settle neatly on the ground (no falling over or rolling around). In short, there is more weight on the barbell on the way down than on the way up.
Very hard to find in the USA.
If purchased from overseas, they will likely cost you $400+, after shipping.
