Summary
Jeff Cavalier introduces the “Draw Bridge,” an all-in-one core exercise that combines plank position, rotation, and a dumbbell to simultaneously train the abs, obliques, and shoulder stabilizers. The movement is a plank variation requiring two benches and a dumbbell, making it a highly efficient compound core exercise. It is presented as one of the most challenging and comprehensive core exercises in the AthleanX program.
Key Points
- The Draw Bridge targets multiple muscle groups at once: abdominals, obliques, pillar strength (lateral core), and the shoulder
- Plank variations are highly effective for ab activation because the core must contract to prevent the lower back from sagging
- Adding rotation to core exercises increases oblique engagement — a training principle Jeff consistently emphasizes
- Holding a dumbbell during the movement adds a loaded eccentric shoulder component, increasing upper body demand
- The exercise progresses from a standard plank into a side plank position, requiring lateral core stability throughout
- Controlled movement is essential — particularly on the way down, where the eccentric phase of the shoulder exercise occurs
- Only two benches and one dumbbell are needed, making this a relatively accessible but high-value movement
Exercise Details
Exercise Name: The Draw Bridge
Target Muscles
- Abdominals
- Obliques
- Lateral core / pillar strength
- Shoulder stabilizers (eccentric loading)
Proper Form Cues
- Begin in a plank position with one arm supported and the other holding a dumbbell at the bottom
- Contract the abs throughout — do not allow the lower back to sag at any point
- Rotate through the torso, sweeping the dumbbell up and around until you reach a full side plank position
- At the top, ensure the body is level and even — avoid sagging at the hips
- Control the descent back to the starting position, emphasizing the eccentric phase
Common Mistakes to Avoid
- Allowing the lower back to sag in the plank position (indicates insufficient ab engagement)
- Sagging the hips during the side plank portion
- Rushing through the movement — the eccentric (lowering) phase should be deliberate and controlled
Sets / Reps
- 3–4 sets recommended
- Work both sides equally
