Description
A core strengthening exercise where you lie on your back with a weight, extending your opposite arm and leg while keeping the other arm and leg bent at a 90 degree angle, then switch.
How to Do Weighted Dead Bug
- 1Setup
Lie supine on a mat, pressing your lower back firmly into the floor. Hold a dumbbell or weight plate with both hands directly over your chest, arms extended.
- 2Setup
Lift your legs so your hips and knees are bent at 90 degrees, with your shins parallel to the floor. This is your starting position.
- 3
Slowly lower your right arm (holding the weight overhead) and left leg towards the floor simultaneously. Exhale as you extend, ensuring your lower back remains pressed against the mat.
- 4
Stop just before your hand and foot touch the floor, then slowly and with control, return them to the starting position, inhaling.
- 5
Repeat the movement on the opposite side, extending your left arm (with the weight) and right leg. Maintain continuous core engagement throughout the entire set.
Tips
- Breathe intentionally: Exhale as you extend your limbs to help engage your deep core muscles, and inhale as you return to the start.
- Maintain constant tension: Focus on keeping your lower back pressed into the floor throughout the entire movement; any arching indicates a loss of core engagement.
- Control the descent: Perform the lowering phase slowly and deliberately, taking at least 2-3 seconds to extend, to maximize time under tension and core activation.
- Keep the weight stable: Ensure the weight remains directly over your chest and does not drift from side to side as you extend one arm, indicating good shoulder stability.
Common Mistakes
- ×Arching the lower back: To fix this, reduce the range of motion of your extended limbs, only going as far as you can while keeping your lower back glued to the floor.
- ×Rushing the movement: To fix this, slow down the eccentric (lowering) phase significantly and focus on controlled, deliberate limb extension and return.
- ×Letting the weight drift: To fix this, actively press the weight straight up towards the ceiling, maintaining a stable shoulder position throughout the exercise.
