Garmin Index S2 Bodyweight Scale

You step on the scale every morning. You see a number. But is that number telling you the full story about your training? Here's what most athletes don't consider: weight is just one data point in a much bigger picture. Body composition—the ratio of muscle to fat, your hydration levels, even your skeletal muscle mass—can reveal whether your training is building performance or just burning you down.

The Garmin Index™ S2 Smart Scale is the only scale built specifically for the Garmin ecosystem that gives you the complete picture.

The Scale That Measures More

Better Metrics – Every time you step on, you get accurate measurements of weight, body fat percentage, skeletal muscle mass, bone mass, body water percentage, and BMI—all synced automatically to Garmin Connect via WiFi. No apps to open. No data to manually enter. Just step on and your metrics are waiting in your dashboard alongside your training load, recovery status, and performance trends.

The Athlete's Edge – The crisp color display shows your 30-day weight trend right on the scale, so you can see if you're on track for race weight without pulling out your phone. And unlike basic bathroom scales, the Index S2 uses bioelectrical impedance analysis to measure what matters: are you losing fat or muscle? Are you properly hydrated before that long run? Is your bone density holding up through high-volume training?

Built for Training Cycles – The scale sends a weak electrical current through your body to measure tissue resistance. This data, combined with Garmin's athlete-specific algorithms, gives you insights that help you adjust nutrition timing, track recovery quality, and monitor body composition changes across build phases, peak weeks, and taper periods. The 9-month battery life means one less thing to worry about during race season.
