The sensors, requiring one AAA battery each, strap onto your left arm and right leg, and they read your movement and also track your heart rate. They replace the Nunchuk, used in the two previous entries. You were required to detach and reattach the Nunchuk often, and also take it in and out of the leg strap for practically every other exercise. In Active 2.0 you strap on the sensors while you get prepared for your workout, and you're good to go. They add better freedom of motion, as there is no cord to get in the way, and they're also more responsive and make it harder to cheat.
Along with the new peripherals, the game also features more of a sport focus than in previous titles. There are different types of exercises that make the experience more of a game. You can now head soccer balls into a net while performing jump squats, or do lunges while trying to defend a goal in the soccer set of exercises. You can also combine the two and shoot a foul shot in the basketball set.
Active 2.0 will also feature a new nine-week program, which is divided into three different sections that focus on specific parts of your body. There will also be an involved online hub, but the specifics are unknown right now.
EA Sports Active 2.0 will come bundled with a new stronger resistance band and two wireless motion sensors. It hits stores this fall.
