- Rep-based
- Back

The Weighted Bag Spin is a dynamic, full-body rotational exercise that builds explosive core power, shoulder mobility, and coordination. It forces the obliques and stabilizers to work together to manage momentum as the weight moves through a 360-degree arc.

Setup
- Stand with your feet slightly wider than shoulder-width apart and a slight bend in your knees.
- Grip the weight (plate or bag) firmly with both hands in front of your midsection.
- Engage your core and pull your shoulder blades down and back to create a stable base.
How to do it
- Swing the weight across your body and upward in a large circular arc, passing it over one shoulder and behind your head.
- Complete the circle by bringing the weight over the opposite shoulder and back down to the starting position near your hips.
- Exhale forcefully as you drive the weight upward and inhale as it descends back to the front.
- Maintain a fluid, rhythmic tempo, using your hips and quadriceps to help drive and absorb the momentum.
Form checklist
- Keep your core braced throughout to prevent the weight from pulling your lower back into an arch.
- Ensure the weight clears your head safely without tilting your neck forward.
- Allow your hips to pivot slightly on the balls of your feet to reduce torque on the knee joints.
- Keep a slight bend in the elbows; do not lock them out during the rotation.
Pro tips
- Focus on 'pulling' the weight with your obliques and traps rather than just using your arms to move the load.
- Keep the weight as close to your body as possible during the 'behind the head' phase to maximize shoulder stability and control.
Make it harder
- Perform the movement from a staggered stance or a shallow lunge to increase the demand on the quadriceps and balance.
- Increase the speed of the rotation to turn the exercise into a high-intensity metabolic and power-focused movement.
Frequently asked
- What muscles does the weighted bag spin work?
- The weighted bag spin primarily targets the erector spinae, lats, obliques, and serratus anterior, and also works the abs, deltoids, and trapezius as secondary muscles.
- What equipment do you need for the weighted bag spin?
- The weighted bag spin uses weight plate.
- Is the weighted bag spin good for beginners?
- The weighted bag spin is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
