Thigh Master

For serious gym-goers, toned, strong thighs are essential. That's where thigh trainers like the Thigh Master come in. Simply strap these gadgets onto your thighs, squeeze them together, then spread them apart, and repeat.

The cool part? You can use them while jamming to music or diving into a good book. A $10-$17 Thigh Master lets you swap out gym leg days for chill thigh sessions.
