While most people associate workouts with sweating and muscle burn, a small percentage experience something unexpected—what researchers call an “exercise-induced orgasm” (EIO), commonly referred to as a coregasm.
What Is a Coregasm?
A coregasm occurs when deep pelvic floor muscles are intensely engaged during exercise, particularly core-heavy movements like leg raises, crunches, and squats. According to sex researcher Dr. Debby Herbenick, around 10% of people—regardless of gender—report experiencing this phenomenon. Though the exact physiological mechanism remains unclear, it’s believed that sustained core engagement and muscle fatigue play a role.
Exercises That May Trigger Coregasms
While not common, coregasms are more likely to occur during exercises that strongly activate the lower abdominal and pelvic floor muscles, including:
- Hanging leg raises
- Weighted squats
- Hip thrusts
- Knee lifts
- Crunches and sit-ups
Weightlifting, pull-ups, and climbing have also been linked to this response in some individuals.
The Role of the Pelvic Floor
The pelvic floor plays a crucial role in core stability, posture, and overall functional strength. Some fitness experts suggest that people with well-conditioned pelvic floor muscles may be more likely to experience heightened sensation during exercise. This is why disciplines like Pilates, which emphasise deep core activation, have been associated with the phenomenon.
Is It Something to Worry About?
Coregasms are completely natural and not an indicator of any medical condition. They’re simply a byproduct of how the nervous system and muscular contractions interact during certain movements. However, if you experience discomfort or involuntary muscle contractions beyond what feels normal, consulting a physical therapist or doctor specializing in pelvic health may be beneficial.
Core Strength
While coregasms may seem unusual, they highlight the complex connection between muscular engagement and the nervous system. Whether or not you’ve ever experienced one, strengthening the core and pelvic floor remains essential for overall fitness, stability, and injury prevention.
