Your thighs are home to some of the largest and most powerful muscles in your body -- the quadriceps and hamstrings. They also contain smaller muscles along the inner and outer thighs that can cause big problems if weakened or tight. If you have chronically tight thigh muscles or delayed-onset muscle soreness from a tough workout, regularly stretching sore stiff muscles can relive pain and improve mobility.
Dynamic stretches involve movement. They bring the muscle through its full range of motion, getting the blood flowing and bringing blood to the muscles. They're the most effective stretch to do before you workout, when your muscles might still be feeling tender from a previous workout.
After a hard workout or a tough day at the office, ease your tired thigh muscles with a few static stretches. These stretches are held for 20 to 60 seconds to allow the muscle to release.
