FitDeck Exercise Playing Cards
The FitDeck Exercise Playing Cards ($10-$15) are an interesting take on getting in shape without equipment. These stacks of playing cards contain illustrations and instructions describing different exercises, stretches, and movements that require only your bodyweight to perform, but still allow you to build and tone muscle and increase flexibility effectively. There's even a FitDeck with exercises you can do in the office, helping to increase blood circulation, keep muscles limber, and eliminate the stress that's part and parcel of a modern office job. And then there's the Navy SEAL FitDeck.
