In order to build a tough body, you need to track your workout and follow a plan. The SmartIRON Workout Tracker is a cool gizmo that plans, records, and backups your moves. It is a virtual personal trainer that tracks your moves, uploads your data, and helps you set goals.
The SmartIRON tracker attaches to your equipment with its internal magnets and counts reps and sets. Once done, you can upload your data for future references. This cool project is being funded on Kickstarter.
