The hamstring muscles are typically strengthened by bending the knee (i.e., hamstring/leg curl).  However, this exercise does not strengthen the hamstring muscles appropriately to help decrease stress to the lower back and knee during real-life activities like bending, walking, running, etc. when the knee straightens and the hips flex/bend.  In this short video blog from Justin Price (creator of The BioMechanics Method) he teaches you how the hamstrings work to slow down stress to the knee and back and demonstrates an effective exercise (with warm-up) you can integrate into your client’s corrective exercise program to help their lower back, hip and knee function and feel a lot better.
