The final exercise in our protect your knees series focuses on building strength in your hamstrings, on the back of your upper leg. This is the last piece of the puzzle in terms of the major muscles above and below the knees that we want to get strong to help protect the knees.
Unless you specifically train your hamstrings to contract or you sprint regularly, chances are they are going to be short and weak and susceptible to injuries such as hamstring strains or tears, if you suddenly put large loads through them (like the parents race at school sports day!). The standing hamstring curl is a great entry level hamstring exercise.
