I make it a priority to work on my core strength. It's essential to overall strength and fitness, and developing the upper body muscles helps me to lift heavier weights and move efficiently, as part of my regular CrossFit workouts.
As someone who works a desk job, I also spend a lot of time sitting down and often deal with lower-back pain. Building strong core muscles is one of the best things you can do if you're in the same position, as these muscles support the back and minimize the damage of constant sitting.
