Leg exercise regardless of how passive it appears to be is better than no exercise.
Easy set up and being able  to raise one end. I purchased it for my wife who was in an automobile accident and still confined to a wheel chair. Since we just received it and only used it twice I can't report on it's benefits other than it's a good place to start on her rehab. It's well made easy to set up and she started using it twice a day for 30 mins. and hope to move the time up to 60 mins. trice a day.
