Are you too busy to workout because you have too much work to do? Try working out while you work with the Treadmill Desk (TR1200 DT) by LifeSpan. It's basically a treadmill with a 46.5″ wide and 31″ deep desk installed. The height of the desk is adjustable and there's even a large armrest to give you stability as you type. The development molecular biologist, Dr. John Medina, had the idea of the treadmill desk in his book Brain Rules though we don't know if he has anything to do with the one here. If you already have a treadmill, then all you need is the desk; check out the TrekDesk. Apparently studies have shown that aerobic exercise can improve brain functions. Go figure.
