Best Knee Strengthening Exercises

1. Straight leg raises

The straight leg raises help to strengthen your quadriceps muscles, which are the muscles just in front of the thigh. These muscles help to absorb shock before it gets to the knee, decreasing the strain on the knee and helping to reduce pain.
