Group Stretching is a new activity in New Horizons 2.0 that you can participate in by using the tape deck in front of the Resident Services building
Overview
Group Stretching can be done with body movement using Joy-Cons, or can be done in button-only mode.
How to Start Group Stretching
Use the tape deck in front of the Resident Services Building to start a group stretching session. Choose if you want to participate by just pressing buttons or if you want to participate with motion, and the session will begin.
Motion Session
If you choose to do a motion session, detach Joy-Con (R) and hold it in your right hand. After you start the session, look at the prompts on the screen and watch what the characters in the plaza are doing, and follow along with their movements while holding Joy-Con (R) in your right hand. Don't worry if you have trouble matching their movements; there is no penalty.
Button Session
If you choose to do a button session, watch the prompts on screen to see which buttons to press and how to move the L control stick. Try to press the buttons and tilt the control stick to match the movements of the characters in the plaza. Don't worry if you have trouble matching their movements; there is no penalty.
