Ropeless Jump Rope
Who needs a rope to jump rope? JumpSnap, a set of electronic handles, emits a snapping sound for each jump and tracks number of jumps, calories burned, etc. (Can your jump rope do that?) The handles also can be weighted with a set of weights to add resistance. Kit includes handles, weights, an eat-smart guide, a workout DVD, and a travel bag. $39.95.
SUN MONITOR
The sun gods only know how this works—disposable wristbands, dubbed UVSunSense, measure your exposure to harmful UVA and UVB radiation by changing colors to let you know when it’s time to reapply sunscreen, cover up, or get out of the sun. $6.99 (pack of 7).
MUSCLE Scale
For the weight-obsessed: AllegroMedical’s body- composition scale doesn’t just measure weight but calculates body fat, body water, and muscle percentages, and displays them all on a large, easy-to-read LCD. It even suggests daily caloric limits. $32.95.
