Exclusive | The exact 7-day workout plan this fitness trainer used for her Sports Illustrated Swimsuit shoot

If you’ve ever dreamed of being featured in a bikini on an iconic magazine cover, Sports Illustrated Swimsuit model Katie Austin is here to tell you — it’s not that hard.The magazine unveiled its four 2025 covers this week featuring Salma Hayek, Olympian Jordan Chiles, NCAA gymnast Livvy Dunne and model Lauren Chan — and Austin is back inside the issue for the fifth year in a row.The 31-year-old — who is also the daughter of legendary aerobics instructor Denise Austin and a fitness influencer with over 457,000 Instagram followers — spoke to The Post about the routine she follows to get in shape in the days leading up to the shoot.“First off, I just want to say that SI Swimsuit is always the most inclusive and accepts you for whoever you are and whatever body type you have,” she said.“It’s nothing about, ‘Oh, I need to lose weight,’ or ‘I need to eat better to look perfect for the shoot.'”That means the lead-up is less about shedding pounds than it is about shedding self-doubt.

“It’s more about heading into the shoot feeling my best, feeling my strongest, most confident and comfortable on set,” she said.That being said, there is some exercise involved, which is why she recently launched her “Swimsuit Strong: Seven-Day Body Boost” program, revealing the precise exercises she did in the week before her shoot last year.“It’s a little less than 40 minutes per day, but those are the exact workouts I did,” she said.The entire program — which is available on her app — combines Pilates, cardio and strength training for a fast and effective full-body sculpt.The key is to stick with it.

“The one thing I do the week before the shoot is make sure I work out every day,” she said.“I eat intuitively all the time and stay consistent with my workouts.

I also make sure I walk for at least 20 to 30 minutes every day for my mental health.I think being in a great mental headspace before the shoot is really important.
