Still tracking your sets and reps with pen and paper? It’s about time working out went digital. SmartIRON is a virtual personal trainer that sticks to your dumbbells and barbells using its built-in magnets (or to non-metallic equipment with the included adapter) and counts your reps for you, automatically uploading your results to the cloud for access from an internet-connected computer or smartphone. Other features include a rugged machined aluminum casing, large illuminated display, and roughly 10 hours of battery life on a single charge.Learn more at Kickstarter – $100
