Sitting Side Step Tuck On A Padded Stool
- Intermediate
- Compound
- Rep-based
- Waist
This dynamic core exercise targets the lower abdominals and obliques by combining a knee tuck with a lateral 'stepping' motion. Using a dumbbell between the feet adds significant resistance to the hip flexors and quadriceps, increasing the intensity of the compound movement.

Setup
- Sit on the edge of a padded stool or flat bench, gripping the sides behind your hips for stability.
- Place a light dumbbell vertically on the floor and secure it firmly between your feet, squeezing it with your arches.
- Lean your torso back at a 45-degree angle to engage your core and lift your feet off the floor, extending your legs slightly to one side of the stool's midline.
How to do it
- Exhale as you pull your knees toward your chest in a tucking motion, lifting the dumbbell up and over an imaginary center point.
- Inhale as you extend your legs back out to the opposite side without letting the dumbbell touch the floor.
- Reverse the movement, tucking the knees back in and 'stepping' the weight back to the starting side in a controlled, rhythmic arc.
- Maintain a steady tempo, focusing on a 1-second tuck and a 2-second extension.
Form checklist
- Keep your chest lifted and avoid rounding your spine as you tuck.
- Maintain constant tension on the dumbbell by squeezing your feet together throughout the set.
- Ensure the movement is driven by your abs and hips rather than momentum.
- Keep your feet elevated off the ground for the entire duration of the exercise.
Pro tips
- Focus on the 'peak contraction' by squeezing your abs hard at the top of the tuck as you transition sides.
- Visualize drawing a wide 'U' or 'rainbow' shape with the dumbbell to maximize oblique activation during the lateral phase.
Make it harder
- Increase the weight of the dumbbell held between your feet.
- Perform the movement with your hands hovering off the bench to force your core to stabilize your entire body weight.
