Hello Lanephillips0!
There are many ways in which we can improve our posture, some of which may be simple or difficult. The first and easiest way to maintain a better walking stride is to stand up straight, and keep your eyes forward. The second way is to keep your shoulders back and steady, which will help align your spine. The final and hardest way is to suck in your stomach and wear a back compressor.
Hope this will help you out!
