Daily training ranges from 10-40 minutes and offers both Normal and Fast mode. The game software estimates your approximate BMI and daily calories burned so you can track your progress. Choose from a diverse group of trainers and customize their look with unlockable trainer outfits. As you progress, you can earn more songs and more challenging training circuits. If you prefer to work out with a buddy, you can use two sets of Joy-Con controllers or share a pair to enjoy working out cooperatively or test your skills by facing off against each other in a virtual ring!
