Students invent device for the perfect bicep curl

To achieve buff biceps, proper form for strength-training exercises is key, and people often turn to professional trainers to correct them and prevent injury. Cornell student engineers have developed an alternative: A simple electronic device that guides the user through a proper bicep curl.

[...]

The haptic exercise coach, which looks a bit like a blood pressure cuff, has two accelerometers that attach to the wrist and upper arm and track the wearer's movements. A microcontroller takes data from the accelerometers. When the wearer's form goes out of line with pre-calibrated specifications, the device vibrates in two places, alerting the wearer to adjust his or her form. By keeping proper form, the chance for injury diminishes, say the inventors.
