Katie Austin’s TikTok is truly the gift that never stops giving. She shares hilarious influencer content, relatable relationship posts, delicious recipes and the best workouts for any mood or situation you might be in.

Her latest fitness TikTok included an equipment-free and no-jumping cardio HIIT (high-intensity interval training) exercise containing five full-body moves that are ideal for an apartment setting or while traveling.

The 2023 SI Swimsuit model, who was named co-Rookie of the Year in 2022 after winning the Swim Search open casting call the year before, shared the 20-second clip with her 734,000 TikTok followers. The video was set to a remix of Kanye West’s “Gold Digger” and Los Del Río’s “Macarena.”

Austin’s workout is as follows:

  1. Double-cross punch
  2. V crunches
  3. Lunge to knee drives
  4. Tricep dip to toe taps
  5. Windmills

The 29-year-old, who recently got engaged to her longtime boyfriend, Lane Armstrong, encouraged her followers to perform each move for 30 seconds with a 15-second rest in between. Then, repeat the entire five-move set a total of three times.
