The leg extension is a vital movement in strengthening your
quads and patellar ligament giving your knee added stability.
The leg curl trains the often-neglected hamstrings
protecting you from injury, increasing leg strength, greater flexibility and
relief from back pain.
Strengthen your quadriceps muscles with the leg extension
exercise and work your glutes and hamstring muscles with the leg curl. The
transition between the two movements is simple and easy, allowing you maximum
time for your workout.
