Denise Austin, renowned fitness expert and mother of Sports Illustrated swimsuit model Katie Austin, recently shared some effective workout routines to help you achieve your summer fitness goals. With pool parties and beach days just around the corner, Austin's targeted exercises focus on key areas like abs, lower body, and cardio.

One eight-minute ab workout, designed to strengthen and tone the lower body, incorporates lunges and leg lifts to target inner and outer thighs, glutes, and hamstrings. Austin emphasizes that incorporating this routine can help reduce cellulite and build lean muscle.

For core strengthening, Austin recommends four key moves: standing side crunch, bicycle crunch, knee crunch, and plank with leg lift. These exercises engage the entire core and help achieve toned abs. She suggests adding these moves to your regular routine for optimal results.

Austin also shared a low-impact cardio workout perfect for burning calories and boosting metabolism from the comfort of your living room. This under-10-minute routine is easy on the joints while effectively engaging arm and leg muscles simultaneously, maximizing calorie burn in a shorter time.

Austin's commitment to 30-minute workouts over the past four decades underscores her belief in their effectiveness. She alternates between cardio and toning/stretching workouts to maintain a balanced fitness regimen. Her recent appearance in the Sports Illustrated Swimsuit Runway Show with her daughter further exemplifies her dedication to fitness and healthy living.
