great idea.

Riiflex weights introduce a new way to add resistance to your Wii, and Wii Fit workouts. Add weight to both the Wii Remote and Wii Nunchuk and make your Wii Fitter.

Riiflex weights combine the durability you would expect from quality fitness gear, and innovative design you’ll appreciate each time you use these in your Wii, and Wii Fit exercise routines. The ergonomic grip provides secure control throughout a broad range of motions.
