An old Chinese proverb says “You are as old as your spine”. This should go without saying but we often don’t move our bodies as if this is true. We get stuck in the same patterns of movements (squats/pushes/pulls etc) which aren’t inherently bad but, there is so much more you can be doing that will help you become a better mover. Performing something like a bridge will inherently help general movement. The biggest problem with people trying to complete a bridge on the floor is that they lack the requisite mobility in the thoracic and end up dumping into the lower back. If you want to perform a bridge then you need to earn your way to that movement. One of the movements most people CAN do is a wall bridge. This movement has a huge carryover to ANY overhead movement is the wall bridge and its variations.
