Suitcase Lunge

The suitcase lunge is a walking or stationary lunge done while holding a single dumbbell at your side, like carrying a suitcase. It trains your quads and glutes on the working leg, while your obliques, forearms, and deeper core work hard to keep you upright and balanced.

Stand tall with your feet about hip-width apart. Hold one dumbbell in one hand, arm straight down at your side, palm facing your body. Keep your shoulders level, chest up, and eyes forward. Brace your midsection so your torso does not slump toward the loaded side.

Take a controlled step forward with one foot. Lower your hips until both knees are bent to roughly a right angle, with your front knee tracking over your front toes and your back knee hovering just above the floor. Push through your entire front foot to stand back up, bringing your back foot forward to meet the front foot. Keep the dumbbell in the same hand throughout the set, repeating on one side or alternating legs as the workout calls for.

Breathe in and brace your core before each step. Hold that stiffness as you lower, then exhale as you push back up. If you need an easier option, use a lighter dumbbell or switch to reverse lunges. To make it harder, use a heavier dumbbell or take more controlled steps before switching sides.

Fault: The dumbbell pulls your torso sideways so your shoulders tilt. Fix: Squeeze your obliques and grip tight on the loaded side, imagine a string pulling the top of your head to the ceiling, and keep your ribs stacked over your hips.

Fault: Your steps are short and choppy, forcing your front knee too far forward. Fix: Take slightly longer, even steps so your front shin stays fairly vertical and both knees bend smoothly under control.

Fault: You twist or lean your upper body to balance the weight. Fix: Keep both shoulders facing forward and level, letting your core and legs stabilize the load rather than swinging your arms or rotating your torso.
