  3. Tricep kickbacks
  4. Cross punches

Third set

Austin then concluded the workout with a cool down walk on the treadmill. And while she didn’t provide exact timeframes for each movement, Austin demonstrated each in her Instagram reel.

“This Arms + Abs Tread Interval is the perfect combo of cardio & toning! Give it a try and tell me what you think 🤩🤩,” she wrote in her caption.

“I can’t wait for this !!!” one fan declared in the comments section.
