The answer is “Yes”, there are several exercises that can be used as an alternative to squats if you have sensitive joints. Here are a few examples: lunges, step-ups, leg presses, knee extension machines, Bulgarian split squats, and gluteus bridges. It's important to note that proper form and technique are essential for any exercise, especially if you have sensitive joints. It is key to listen to your body and avoid any movement that causes pain. If you have knee joint issues like swelling producing stiffness, redness around the knee, bruising, warmth to the touch, acute weakness, instability, painful crunching or popping noises, or inability to fully straighten the knee, it would be highly recommended and helpful for you to go to a health provider or physical therapist to ensure you are OK to perform squats or knee bending exercises safely and effectively.
