Bring new levels of convenience and enhancement to your Wii Fit workouts with the Pulse Pak from Mad Catz. A heart rate monitor enables you to measure your pulse and gives you a more accurate assessment of your fitness progress from workout to workout than the game alone. The lightweight holster clips onto your workout clothing and keeps your Wii Remote securely within reach while providing button access, giving you the freedom to perform your best workouts without the worries of dropping your controller or having to set it down repeatedly when all you want to do is burn some calories or improve your balance.
