A Form-Correcting Device for Weightlifting

Overview

Maintaining proper form during weightlifting is important for progressing with training. Lifting heavier weights with incorrect form can reduce training efficacy, exercise the wrong muscles, or even cause injury. However, not everybody has access to a personal trainer who can ensure proper weightlifting form. T o address this need, the engineering goal was to build a wearable apparatus that guides beginner weightlifters by helping them maintain proper form while performing deadlifts. The apparatus consisted of a wearable device and a mobile app that worked in conjunction to meet the goal. The device analyzed the wearer’s form using inertial measurement units, utilized an algorithm to determine what type of feedback the user needed, and sent this information to an app. There, this feedback was displayed, along with visuals of the user’s posture, so they would get a better understanding of their form. Additionally, the device was constructed in layers to be comfortable to wear. T o determine whether the engineering goal was met, participants were asked to evaluate several characteristics. The device comfort level and app user-friendliness were rated highly by the participants, indicating that the design interface was satisfactory. The device effectiveness and app usefulness were also satisfactory, but improvements could be made to the accuracy of the feedback algorithm. Overall, the engineering goal was met, and possibilities for future development include adapting the design for a variety of exercises.
