The Revolution Leg Sled Machine is a great alternative to a 45 degree Leg Press.  It has a more compact design, making it an ideal space saver in your gym area.  It has an adjustable oversized foot platform that allows you to adopt a variety of different leg, foot and knee positions.  The Revolution Leg Sled Machine can allow you to load more weight onto your quads without putting the extra stress on your lower back or shoulders like with barbell squats.  This machine is perfect for any gym set up.
