Getting started is often the hardest part of any exercise program, and you’ve already taken that first step — good for you.
Knee pain after adding squats to your workout can be caused by a number of things. For example, you may be doing too much, too soon; your workload may be too heavy; and/or your body alignment while performing squats may be incorrect. In addition, your knee joint may have been unstable before adding squats to your routine, and adding a heavy workload may have aggravated the problem.
Whatever the case, since you are experiencing persistent pain, you need to be evaluated by a medical professional — so considering making an appointment with your health care provider.
Beginners often benefit from a pre-conditioning program to address joint stability and mobility issues before progressing to more advanced levels of exercise. A certified fitness professional can design a safe and effective strength training program tailored to your needs — and reduce your risk of landing on the sidelines with another injury.
