Train smarter: Improve your sit-up performance with core exercises

Sit-ups are are a component of the current fitness test for all 5 branches of Service, but they are considered a “high-stress” exercise for the spine. The good news is, there are several core-strengthening alternatives to sit-ups that could give you just as much—if not more—fitness bang for your exercise buck and help you improve your sit-up performance.

Effective core training actually requires less movement, less need for sit-ups, and more deep breathing and activation exercises.

Core-activation exercises, such as bridging, planks, squats, and lunges, improve your muscular endurance and better match how your muscles function to stablize your trunk and spine during everyday tasks. As your core stability improves, your body becomes more resilient to fatigue—one reason why these exercises can help improve sit-up performance.

Statistically speaking, a military unit that practices core-stability exercises should have more members who pass the sit-up component of a PT test than those who practice sit-ups. Also, performing core-stability exercises might reduce the number of lost-duty days if you happen to get injured.

Bottom line

Core strength is important for more than just the sit-up part of your PT test. A strong core can improve posture and athletic performance, and help decrease back pain.
