One of the biggest training tips that my personal trainer gives me is having the correct posture when going through our workout regime. If you have incorrect posture not only are you not doing your exercises properly but you are putting unnecessary strain on your neck shoulders and back. A recumbent exercise bike will alleviate the stress from poor posture.
A Recumbent exercise bike differs from the average gym bike in that it has extra back support attached to the bike seat. You are able to relax back in to the seat whilst you pedal which can aid in correcting bad posture or relieving tension from those with chronic neck and back pain.
