How Many Calories Do Sit-Ups Burn?

A 15-minute vigorous sit-up session burns approximately 90-130 calories. Sit-ups engage not only the core but also the hip flexors, making them a dynamic movement that elevates heart rate when performed at high volume.

Sit-ups have been a staple of fitness testing and military training for decades. Unlike crunches, which isolate the abdominals, sit-ups involve a full trunk flexion that requires coordination between the rectus abdominis, hip flexors, and stabilizer muscles throughout the entire core.

Our calculator uses 2024 Metabolic Equivalent of Task (MET) indices for calisthenics. Sit-up intensity ranges from MET 3.8 for light pace to MET 9.5 for circuit-style HIIT sessions. This places vigorous sit-ups on par with moderate Pilates or low-impact aerobics.

Factors Influencing Sit-Up Calorie Burn

Range of Motion

Full sit-ups (shoulder blades touch the floor) burn more calories than partial sit-ups or crunches.

Repetition Tempo

Fast-paced, continuous reps elevate the heart rate more, increasing aerobic calorie burn.

Added Resistance

Holding a weight plate or medicine ball increases the load on the core muscles, raising MET values.

Decline Angle

Performing sit-ups on a decline bench increases the gravitational resistance, making the movement more challenging.
