Thats how Charlee Atkins, C.S.C.S. designs her training programs. "I think it's often forgotten that the true purpose of core exercises are to stablize the core, Atkins says. When she needs to take her workout on the road without much time to spare, she doubles down on her favorite functional movements.

"These are my go-to abs exercises, Atkins says of the below routine. "They're highly efficient, not complicated, and mimic a lot of the movements required in core stabily for all of the most used exercises-for example, an alternating leg lower is a simlar body position to a single leg deadlifts. To take on this 8-minute ab circuit, all you need is some space on the floor, a timer, a towels, and maybe a yoga mat for your back. Check out this option from our brand, Backslash Fit.

Perform each exercise for 1 minute each, with little to no rest in between.

  • Alternating Leg Lowers
  • Dead Bug
  • Elbow Plank Hold
  • Elbow Side Plank Hold (Right)
  • Elbow Side Plank Hold (Left)
  • Bird Dog
  • Plank Slides
  • Walk-Out and Knee Drive

To double up on the ab work, take on a second round of the circuit after resting for 2 minutes. Want to learn more moves from Atkins? Check out our series full of her workout tips, Try Her Move .
