Regularly performing an exercise like two legs to chest is a great way or relieving back pain.
These days most of us spend a lot of time in unnatural positions - sitting in a car, at a PC, even watching TV. Our bodies simply weren't designed to do these things for hours at a time.
Two legs to chest is a gentle way to unwind the spine and relieve some of the pressure that can build up through the day. It is also a great exercise for people who have suffered a back injury and need to restore a natural range or motion.
To perform this stretch, lie down on your back on a comfortable surface (carpeted floor or exercise mat). Slowly bend both knees into your chest, using your hands to assist you. Pause for ten to twenty seconds while gently hugging your legs, then slowly lower your legs back to the floor.
This exercise will relieve pressure and pain in the lower back, and also stretches the gluteals (butt). You can do 5 to 10 repetitions up to three times per day.
As with all back exercises, you should stretch to the point of tightness, but never to the point of pain.
