Self Pop Your Upper Back in Seconds #Shorts

Here's an easy exercise that may end in a 
satisfying self pop, crack, or release in the upper   back. Lie flat on your back with a large rolled up 
bath towel over the spot that you're focusing on.   From there, we're going to slide backward until 
that spot is at the edge of a bed. Take your hands,   place them on the back of your head. Allow gravity 
to take your head weight and upper body weight   downward as much as we can, until we feel a deep 
opening stretch. If that segment is locked up, you   might get that sudden pop you are looking for. This 
is how we can take it to the next level. Press down   with your head and wing your elbows down towards 
the floor until you feel a deep stretch. Do not try   to force the pop with this one. Instead, hold this 
comfortably for 15 to 20 seconds. From there, you   can relax and then repeat this three to five times, 
and you can switch over different spots as needed.
