For gym enthusiasts lifting heavy weights, bad form can result in weeks off from the gym. However, injuries are not always instant and even the slightest odd angle in a squat, repeated over time, can result in debilitating pain.
A smart weight that “talks” to the user, using sound, would be ideal to help correct lifting form. Gyroscopic sensors that detect movement, angle and altitude can be used for a variety of exercises to determine proper form. If the user’s form is off, the weight will speak to them, making a different sound for different aspects of form that are not correct.Proof of Concept
A gyroscope and microphone simulates a barbell weight. When the bar is tilted left, the pitch of the sound goes up, when the barbell is tilted right, the pitch goes down. A button is used to simulate grip, telling the system to begin recording accelerometer data.
