The Short Version
Garmin Connect+ announced a performance dashboard overlaying training data with sleep, stress, and heart rate metrics in one view.
Garmin Connect+ puts workout data and wellness numbers, like sleep quality, stress levels, and heart rate, on one screen so you can see whether your training is actually helping or quietly wearing you down. Most fitness apps hand you a pile of numbers with no way to connect them. Garmin is showing you the relationship between the numbers, which is the part that actually changes behavior.
