When it comes to building a strong, functional core, most people instinctively think of sit-ups or crunches. A strong core is foundational to total-body strength and stability but when it comes to core training, not all ab exercises are created equal. While floor crunches have long been a staple in the fitness community, trainers and enthusiasts alike are pivoting toward a more dynamic and effective approach: standing core workouts.This isn’t just about aesthetic abs. Standing ab workouts engage more muscles, improve balance, and reflect the way we use our core in daily activities. Fitness expert and YouTuber Maddie Lymburner, shared a workout video on Youtube emphasizes, "I believe in training the core while standing because it forces the abs and the other midsection muscles to engage to keep you stable."A standing abs routine mimics how your core works in daily life—stabilizing, balancing, and powering your every movement. Here’s how you can transform your core training with Maddie’s dynamic, equipment-friendly 15-minute standing abs workout.Why Standing Core Workouts Is Better Than Crunches?Traditional floor exercises like crunches and sit-ups isolate the rectus abdominis, but they don’t fully engage the muscles that stabilize your spine and pelvis during real-world activities. Standing workouts, on the other hand, challenge your entire core—including the obliques, transverse abdominis, and lower back—by forcing your body to balance, twist, and resist gravity.“Training your core while standing means your abs have to work the way they’re meant to work,” Maddie explains. “You’re not just lying down; you’re engaging your muscles to keep you upright, balanced, and strong.”One of the best things about this routine is its accessibility. “You can use a dumbbell, a kettlebell, or whatever you have access to at home. It will work fine,” Maddie reassures. “Make sure that you can see your screen so you can follow along with me.”The 15-Minute Standing Abs Workout, Round One1. Single-Arm Dumbbell MarchesStart by holding a dumbbell in your right hand, lifting your right leg up, and lowering it slowly. This move tests your core stability and balance. Switch sides and repeat.2. Standing Twists with DumbbellWith a slight bend in your knees, hold the dumbbell in both hands and twist from side to side. "You're going to feel the resistance from the weight. We're going to work those obliques," says Lymburner.3. Oblique Crunches with DumbbellWith the dumbbell in your right hand, slide it down your leg and return to center. Then raise the weight overhead and lean to the opposite side. Repeat and switch arms. This move targets your side core muscles like no other.4. Diagonal Leg LiftsHolding the dumbbell above your head with both hands, bring one knee diagonally across your body and then open it to the side. "Bring that knee up as close as you can to your chest, and then to the side," Lymburner instructs. Repeat with the other leg.5. WoodchoppersStarting from a low position, bring the dumbbell up diagonally across your body while bracing your core. Repeat on both sides. "Think about using your core to move the body up, not your arms," says Lymburner.6. Standing Elbow-to-Knee CrunchesPlace your fingertips near your ears, bring your knee and elbow together at your center. This simple move is effective for working the entire midsection.7. Dumbbell Passes Around the WaistPass the dumbbell around your body from one hand to the other. The trick is to stabilize your core so the rest of your body doesn’t sway. Go one direction in Round One and switch in Round Two.Standing core exercises are rooted in functional fitness—the idea that training should prepare your body for real-life movements. Research shows that standing ab routines activate more muscle groups, improve posture, and boost calorie burn compared to traditional floor exercises. They also enhance balance, coordination, and athletic performance, making them ideal for everyone from beginners to seasoned athletes.Tips for Getting the Most Out of Your Standing Abs WorkoutFocus on Form: Keep your movements controlled and your core braced throughout each exercise.Breathe: Exhale during the effort phase (e.g., lifting the knee or twisting) to maximize core engagement.Start Light: Use a light weight to master technique before progressing to heavier loads.Stay Consistent: Incorporate this routine 2–3 times per week for best results.So the next time you think of core workouts, skip the mat. As Maddie Lymburner shows us, just a pair of dumbbells and 15 minutes can power up your posture, balance, and abs more efficiently than any crunch circuit ever could.Disclaimer: Always consult with a healthcare provider before beginning any new exercise program, especially if you have any pre-existing conditions or injuries.
