If there’s one thing Jennifer Lopez is known for, aside from her unmistakable Latina confidence, it’s her incredible physique. At 56, the singer and actor continues to look incredibly fit, and much of that comes down to how consistently she prioritizes resistance training. Her core workouts are no exception.
Much of this approach and mindset comes from her time working with New York–based celebrity trainer David Kirsch, who trained Lopez for years alongside clients including Britney Spears, Kate Upton and Heidi Klum.
