Exercise devices that can be worn on the hand or foot utilizing resistance from the air to perform the exercises. The exercise device comprises a fitting member and a resistance member connected to the fitting member. The fitting member is configured to be worn on a limb, such as the hand or foot so that the user does not have to hold anything during the exercise. Additional weights can be added to the exercise device, but the overall apparatus remains small and relatively lightweight so that it may be easily carried in luggage and used on the go.
