Workday workout

My idea, which probably was thought of before, though I could not find it, consists of a series of devices you can wear on your arms & legs, which would essentially increase the resistance and calories burned during everyday taks.

I given the idea reading about atheletes training in lower gravity (in space) would have lesser muscle tone.. if we could take the to the opposite, we could increase muscle tone and give someone that added boost during an event after the devices were removed. sort of like runners who i've seen training for speed events by wearing a small parachute which increase resitance and to be more powerful with the parachute removed.

I was thinking of 2 possible routes to go with this idea either: 1) Weight based: Sleeves that could be worn on the upper arms or lower legs with thin weights that could be added. in the winter or under workout clothes they would not be noticible. Admittedly this is similar to standard ankle or wrist weights which are out now, but they would be designed to be worn under clothes during someone's daily routine.

-or-

2) Resistance based:a second harder to create idea would be to create a device that would increase resistance at joints. a stiffer sleeve over knees or shoulders which would make bending them more of a workout. This can be achived by using various strengths of elastic, or a more interactive device which would incorporate tubes which could be inflated for more resistance with a pnumatic type of device.... This would enable you to add resitance could be added with a few pumps like an inflatible cast...

Ah well, just an idea.. problems I can think of would be health concerns of screwing up your joints with the added stress of either more weight or resistance.
