Power is crucial in most sports.
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.
