Sitting at work all day long is not good for your health. Many health experts suggest people should get up and move their body at work to avoid developing serious health conditions. A sit and stand desk can help. The LifeSpan Fitness C3-DT5 Bike Desk is another piece of equipment you can pick up to do work and get fit. The Bike Desk is Bluetooth-enabled and syncs to your Windows or Mac computer. The seat has 19 height adjustment settings.
The desktop frame is unattached from the bike. It has two rear mounted transport wheels. Not cheap but it can help you get fit.
