First off, what makes this a great lying leg curl is the angle of the pad. It isn’t flat, but pitched downward so that it locks your hips down and keeps your butt from shooting up, so that the tension remains in the hamstrings and not in the low back. The motion itself is as smooth as butter. The leg pad is very comfortable.  And then you add onto that the adjustable cam, the trademark of all Strive machines which allows you to change the tension within the range of motion. All of these factors together make for fantastic lying leg curl. Strive did it again.
