Setup
- Position two sturdy chairs of equal height parallel to each other, slightly wider than shoulder-width apart.
- Place a strong, non-slip bar (like a heavy-duty broomstick or pipe) across the seats or tops of the chairs.
- Lie on your back between the chairs with your chest directly under the bar, using an underhand (supinated) grip at shoulder-width.
- Bend your knees to 90 degrees and place your feet flat on the floor to support your lower body.
How to do it
- Exhale and pull your forehead toward the bar by flexing your elbows, focusing on the 'curl' motion rather than a standard row.
- Keep your hips elevated and your core braced to maintain a straight line from your shoulders to your knees.
- Inhale and slowly lower your body back to the starting position using a 3-second eccentric tempo.
- Maintain a slight bend in the elbows at the bottom of the rep to keep constant tension on the biceps.
Form checklist
- Keep your elbows tucked close to your sides to maximize bicep recruitment.
- Ensure your hips do not sag; keep your glutes squeezed throughout the set.
- Avoid using your legs to drive the movement; they should only provide balance.
- Keep your neck in a neutral position, looking straight up at the bar.
- Check that the chairs and bar are stable and secure before starting every rep.
Pro tips
- Focus on pulling your face to the bar instead of your chest to increase the angle of elbow flexion for better bicep isolation.
- Squeeze your shoulder blades together at the top of the movement to fully engage the trapezius and lats.
Make it harder
- Straighten your legs completely to increase the amount of body weight you are lifting.
- Add a 2-second isometric hold at the peak of the movement to maximize bicep contraction.
