Part of your physical therapy may include performing a regimen of exercises designed to strengthen your muscles. Without exercise, injured muscles and joints may harden, and if the inactivity goes unchecked for a long time, you may end up experiencing irreversible loss of mobility.
With muscle strengthening exercises, it isn't just about the leg muscles but also your core. After all, your core is the body’s center of balance, and it helps to support all other muscles. Strengthening your core with physical therapy exercises will greatly improve your balance and give you a wider range of motion.
