I once attended a fitness salon which had electrically powered machines for exercising each muscle group. A good deal of effort was required on my part but the machine also did a lot of the work. For example on the leg raise machine I lay on the table which had a separate section for each leg. Then the machine was started and each leg was section was raised one at a time. Gradually the settings were adjusted until I was doing most of the work and the machine less. i was greatly overweight at the time and these machines helped me get into condition without too much stress on my joints and especially my heart. I can now exercise independently of the machies but I was talking to an overweight friend about them but I didn't know what they were called. The salon is now closed and I would like to know the name of these machines. Please help. Thankyou. T. Ross.
