DC Blocks by Derrick Crass, two-time Olympian in the sport of weightlifting.

All things being equal, the most powerful athlete wins. Lifting from blocks allows lifters to correctly place their body and the bar in the optimum position to quickly and repeatedly impart the greatest amount of force with the greatest velocity possible. This violent movement develops huge power output that transfers to many sports, especially weightlifting. Incredible power is developed using blocks vs. lifting from the hang position, usually an inefficient position to begin with. Here, in a synopsis by Harvey Newton, Keijo Hakkinen and Heikki Kauhanen present their research, “Changes in Biomechanical Characteristics of Various Snatch Pull Exercises with Various Loads During Five Consecutive Repetitions of One Set,” from International Olympic Lifter (IOL), 1988.

My weightlifting blocks started out at the Belleville Weightlifting Club in 1985 as a series of stacked, unstable wooden 2" x 6"s nailed together to fit my dimensions. Those blocks were lightweight but not interlocking; spectacular crashes happened when I missed a big lift; the blocks, bar, and weights came tumbling down all over the place in a heap.

Today, my weightlifting blocks start out as your scrap plastic. Patented technology uses previously deemed “un-recyclable” plastics in a blending process that grinds the scrap into 1/4" size particulates. The material is processed with patented recycling equipment and ejected in loaves of malleable, warm plastic. These loaves are then placed inside a mold and, using a hydraulic press, the material is squeezed into patented Derrick Crass (DC) Blocks. Each DC Block is cooled while inside the mold and then emerges as one solid, stiff construction with superior impact resistance, strong, stackable, and indestructible.


Each DC Block measures 2" tall x 15.5" wide x 19" long.

Each DC Block weighs approximately 5 kgs (10.5 lbs).

DC Blocks Guarantee

DC Blocks will not chip, crack, break or rust.

DC Blocks are made in the U.S.A.

To utilize the products to their fullest please be mindful of the following:

  • The new design of DC Blocks relies on a crenellated bumper to allow for greater lateral wall strength on the ends while continuing to provide DC Blocks’ unique interlocking stability front to back and top to bottom. Each crenellation allows sideways force attenuation to avoid sidewall blowout.
  • The new crenellated DC Block design will interlock underneath previous version of DC Blocks, but not over.
  • Lift from and return the weights in the middle 1/3 of the DC Block, as if the area from which to lift/return is the middle square of a “tic-tac-toe” game.
  • Return the weights using control.
  • DC Blocks are made with 100% recycled plastic and will not chip, crack, break or rust. Lift in temperatures from 30O to 120O Fahrenheit. Temperatures cooler may increase brittleness and temperatures hotter may lead to excessive softening.
  • The DC Blocks warranty is null and void if they are not used in the above fashion and/or if the blocks are combined with any other piece of equipment, such as on top of wooden jerk boxes.
