I'm a big fan of keeping hand weights by the TV for impromptu lifting sessions, and for all you Wii Fit devotees, the Riiflex Wiimote weights have a similar appeal. These snap-on weights affix to your Wii Remote and Nunchuck accessories to make workouts (or play) more challenging.
Available as a set of two 2-pound weights ($35) or two 4-pound weights ($40), the brightly colored dumbbells look comfy to hold and let you access the Wii's assorted buttons and triggers. Even if you don't have a Wii Fit, you can snap them on your Wiimote to make any Wii game work a little harder.
