Kettler Coach

Price: around £400

On the plus side, this rower is compact, has a decent, if pared down workout computer, and a handy extra back rest that you can place over the rails and use to perform resistance exercises such as the cable pull-over. But the major drawback of its size is that the flywheel housing actually impedes a full recovery from a stroke. This means you can only row to a certain level of intensity because you have to modify your form to avoid slamming the handle into the front of the machine. So perhaps not the best choice for more regular users.
