Rubicon Workout is a powerful upper body session that combines two classic exercises—pull-ups and crunches—to build strength, endurance, and muscle definition. Pull-ups target your back, shoulders, and arms, while crunches focus on your core, creating a balanced, efficient workout that engages your upper body from top to bottom. With just these two movements, you’ll challenge your strength, push your limits, and feel the burn as you progress. Whether you're aiming for improved upper body strength or simply want to mix up your routine, the Rubicon Workout will deliver results.
