Dead Bug with Medicine Ball
Strengthen your core with the Dead Bug, an anti-extension exercise using a medicine ball.
Description
A core exercise where you lie on your back with your arms and legs up, holding a medicine ball. Extend one leg and the opposite arm, alternating sides.
How to Do Dead Bug with Medicine Ball
- 1Setup
Lie on your back with your knees bent at a 90-degree angle, shins parallel to the floor, and hips stacked directly over your knees.
- 2Setup
Extend your arms straight up towards the ceiling, holding a medicine ball firmly between your hands directly over your chest. Ensure your lower back is pressed into the floor.
- 3
Inhale deeply, then as you exhale, slowly extend your right leg forward, hovering it just above the floor, while simultaneously lowering your left arm overhead, hovering it just above the floor.
- 4
Maintain a stable core and keep your lower back pressed into the floor throughout the entire movement. Do not allow your back to arch.
- 5
Inhale as you slowly and with control return your right leg and left arm to the starting position.
- 6
Alternate sides, extending your left leg and right arm, ensuring the movement is controlled by your core rather than momentum.
Tips
- Before starting, gently tilt your pelvis to flatten your lower back against the floor and actively maintain this posterior pelvic tilt throughout the entire exercise.
- Coordinate your breath with the movement: exhale as you extend your limbs to engage your transverse abdominis, and inhale as you slowly return to the starting position.
- Perform each repetition slowly and with deliberate control, focusing on deep core engagement rather than speed to prevent any momentum from assisting the movement.
- Start with a lighter medicine ball to master the form and core stability, gradually increasing the weight only when you can maintain perfect spinal position.
Common Mistakes
- ×Arching the lower back is a common error; actively press your lumbar spine into the mat throughout the entire movement by engaging your core and maintaining a posterior pelvic tilt.
- ×Rushing the movement reduces effectiveness; control both the eccentric (lowering) and concentric (returning) phases to maximize core engagement and stability.
- ×Losing core tension during the transition between sides compromises spinal stability; maintain constant abdominal tension even when bringing limbs back to the start.
