Bestbuy offers Ring Fit Adventure - Nintendo Switch for $34.99 (orig. $79.99) with free shipping.

Product Description:
Explore a fantastical adventure world to defeat a bodybuilding dragon and his minions using real-life exercises. Traverse grass-swept plains by jogging in place, attack enemies with overhead shoulder presses, and refill your health meter by striking some yoga poses. Two new accessories, Ring-Con and Leg Strap, measure your real-world actions and help turn them into in-game movements. With additional mini games, Ring Fit Adventure is a great escape for players of all skill levels and schedules. In the Adventure mode, defeat enemies with attacks based on real-world exercises. As you work through each level (and possibly work up a sweat), you'll earn experience points. Between fights, you may encounter some unusual methods of transportation, such as squat-powered launch pads and more. Want to compete with others? Pass around the Ring-Con accessory, and select from a few mini games: break boxes with gusts of air, craft pottery using squats and more.
