How Many Situps Should You Do in a Day?

Men's Health fitness director Ebenezer Samuel, C.S.C.S., recommends maxing out at 40 sit-ups per day for most people. 

Trying to accomplish 50, 60, or 100 reps makes you curl up and lay down quickly. Thus, form compromises to finish a lot of reps aren't worth it.

To minimize pulling your head and neck when sitting up, Ellis advises keeping your hands at your sides with palms facing up.

Exhaling, raise your upper body toward your knees with your core engaged.

Maintain control as you inhale and slowly lower your upper body.

Sit-ups improve posture and develop the musculature needed for functional movements like bending and lifting, which applies to daily life.

The plank and deadbug focus on the deep transverse abdominis muscles that tighten the midsection, but the sit-up targets the rectus abdominis.

This component of spinal flexion is vital, but too much volume and incorrect form can lead to overdoing it, therefore the ideal amount is smaller than expected.
