How do I get an explosion force to ignore my character's rigidbody?

I have a 2.5D platformer that I'm working on and I want a mechanic where there's an explosion force applied to everything around my character, but not to my character. It's kind of like a sphere of force that pushes everything around him away. Unfortunately, I haven't been able to stop this force from being applied to my character, so when I hit the button, my character goes flying. So how can I get the ExplosionForce to ignore my character's rigidbody/collider?

     // Force Explosion Function
     void ForceExplosion() {
         Vector3 explosionPos = transform.position;
         Collider[] colliders = Physics.OverlapSphere(explosionPos, explosionRadius);
         foreach (Collider hit in colliders) {
             if(hit.rigidbody != null){
                 hit.rigidbody.AddExplosionForce(explosionPower, explosionPos, explosionRadius, explosionUpwards);
             }
         }
     }
