SoulCore is an apostolate that intentionally engages the whole person in the sacred experience of the rosary. Integrating the prayers of the rosary with core strengthening, stretching and functional movements to nourish body & soul and encourage deeper reflection on the virtues. A gentle path to grow in virtue and cultivate interior peace. SoulCore began from a little “yes” to an inspiration of the Holy Spirit. Founded in monotheism, one true God, SoulCore is based in Christian meditation and encourages “filling” the mind & soul specifically with the life, virtues and Word of Christ. A movement all its own, SoulCore is not affiliated with any other fitness disciplines. More specifically, it is not yoga, nor are yoga poses or Sanskrit referenced at any time. Our Lady’s desire is always to lead us closer to her son Jesus. As a Marian apostolate, SoulCore imitates her in striving to draw others closer to Christ through deeper reflection on His life and virtues in the rosary. Anything that could potentially lead us away from Christ is counter to our mission.
