The leg extension machine is a great workout for all types of people, it is even great for building and toning your upper body. I have seen many people that have not been able to complete a workout using the machine, especially those who have had trouble following the instructions.
The basic principle is simple, with the machine you will simply bend your legs at the knee joint. The angle can be changed from a full knee bend up to a half knee bend. It’s a simple exercise that can be done at home. The machine is also great for a variety of other reasons. The machine can be used for a variety of exercises that require very little resistance, such as those used in Pilates.
