Day 3 of our 7-Day Abs Program is all about engaging your abs while standing. That's right, no floor or knee work — just standing exercises! You'll work through 10 exercises for 45 seconds each, and then repeat each one once more. Exercises include standing twists, wood chops, standing knee lifts, and more, which will get your core fired up! Want to elevate your workout? Grab a 10lb dumbbell to add intensity.
