If you’ve been doing tons of sit-ups to build core strength, it might be time to rethink your routine. Sit-ups can strain your lower back and overwork your hip flexors—especially if you’re doing them fast or in high volume.
At Xtra Mile Fitness, we prefer core movements that protect the spine and build real-world strength. Coach Corey shares three of his go-to exercises that anyone can do:
Plank – Builds full-body tension and core bracing
Dead Bug – Strengthens your core while improving control and posture
Bird Dog – Improves balance, stability, and spinal alignment
These are safe, effective, and perfect for all fitness levels.
