Lunges have developed a reputation as a guaranteed way to develop leg and gluteal muscles.
And it’s true.
It is also true that knee pain is a very common outcome of lunges. Improper form and muscle imbalances are usually the culprit.
Without careful attention to form, the knee pain will likely worsen. Often it gets bad enough that exercise has to be put on hold.
And that is not the goal.
If you develop persistent knee pain after doing lunges it is a sign that something is not right.
Don’t ignore this sign. Find another way to strengthen your lower body without damaging your knees. Joint damage is never good!
