The FitVest is a wearable device that monitors and encourages non-exercise activity throughout the day to help users burn calories and stay fit in a low-commitment way. It uses weight-bearing resistance to provide benefits like increased endurance, strength, and bone density without strenuous exercise. The device is modular and contoured to be comfortable, and uses sensors and electrical muscle stimulation to provide biofeedback on activity levels while gamifying daily living. It aims to be an accessible fitness solution for busy adults seeking health benefits with minimal effort.
