The objective of this project is to design an adjustable jerk block capable of being used by athletes with heights ranging from 4’10” to 6’4″, weighs less than conventional jerk blocks, is mobile, easy to ship, easy to adjust, and is able to withstand a 250lb object. An adjustable jerk block is a device that helps weight lifters to perform a “jerk” safely and efficiently. This device can be adjusted from 33 to 54 inches high, hence a perfect product for athletes with heights from 4’10” to 6’4″. It is composed of A36 steel with a damper and is able to withstand more than 6900lbf impact weight resulting from dropping 250lb weight on the platform. This less bulky device weighs 217 pounds with dimensions of 20×48 inches. It can be clamped down to 14 inches for easy shipping while the four casters underneath the base makes it mobile at the gym.
