The Russian twist is a core exercise where you sit, lean back slightly, and rotate your torso side to side. It can train the obliques and trunk control, but it should be done with control rather than speed.
It is not a shortcut for weight loss, immunity, or cardiovascular fitness. Use it as one core exercise inside a balanced routine.
Exercise Overview

The Russian twist can be done with bodyweight, a medicine ball, a dumbbell, or another light load. Beginners should start without weight and keep the feet on the floor.
What It Trains

The movement mainly challenges:
- Obliques.
- Rectus abdominis.
- Hip flexors.
