Setup
- Stand tall with your feet shoulder-width apart and a slight bend in your knees.
- Extend one arm down with the palm facing up, keeping the elbow tucked into your side.
- Place the palm of your opposite hand directly on top of the palm or wrist of the working arm.
How to do it
- Curl your working hand toward your shoulder while simultaneously pressing down firmly with your opposite hand to provide resistance.
- Exhale during the upward phase and squeeze your bicep hard at the peak of the contraction.
- Inhale as you slowly lower your arm back to the start, maintaining constant downward pressure with the resisting hand.
- Complete the full set on one arm before switching to the other.
Form checklist
- Keep your elbows pinned to your ribcage to prevent shoulder involvement.
- Maintain a neutral spine and avoid leaning backward as you curl.
- Ensure the resistance provided by the non-working hand is consistent throughout the entire range of motion.
- Keep your wrists straight and firm to avoid unnecessary joint strain.
Pro tips
- Focus on the 'negative' phase by increasing the downward pressure as you lower the arm to maximize eccentric muscle fiber recruitment.
- Visualize the working bicep peaking as you reach the top of the movement to enhance the mind-muscle connection.
Make it harder
- Incorporate a 5-second isometric hold at the midpoint of each repetition while applying maximum counter-pressure.
- Perform the movement with a 4-second eccentric (lowering) tempo to increase time under tension.
