What is RIS?

The Relative Index for Streetlifting (RIS) provides the definitive method for comparing Streetlifting athletes across weight classes within the same gender. Developed specifically for All-4 competitions, this scoring system normalizes strength performance using comprehensive data from elite competitors. Updated annually to reflect evolving standards, RIS offers a fair benchmark for athletes, coaches, and competition organizers worldwide.

We recalculate RIS with the current formula, so scores may differ from published results.

When bodyweight is missing, we estimate it from the published RIS where possible. Otherwise, we keep the reported score, marked R.
