Omron Alvita Optimized HJ-321 activity tracker

Designed for power walking and aerobic exercise, the Alvita Optimized (HJ-321) counts your aerobic steps separately from normal walking steps, as well as the distance, calories burned, and time you’ve traveled, giving you more information about your overall activity level. It accurately counts every step, using Omron’s Tri-Axis Technology. Just wear it on your hip or place it in your bag or pocket.
