The more you work out, the fitter you'll get. Your VO2max, sometimes described on wearables as a "cardio fitness" score, is a number that tends to be higher among people who are more cardiovascularly fit.

Part of the initial appeal of the Steam Deck is its price: While you could choose a souped-up model with an OLED display and expanded internal storage, you could also pick up an LCD model with a 256GB SSD at a reasonable $399.
