Setup
- Set an adjustable bench to a 30 to 45-degree incline.
- Sit on the bench with a single dumbbell resting on your thigh.
- Kick the dumbbell up to shoulder height as you lie back, keeping your feet planted firmly on the floor for stability.
- Hold the dumbbell with your palm facing forward (or slightly turned in) and extend your non-working arm out to the side to help balance your torso.
How to do it
- Inhale and slowly lower the dumbbell toward the side of your upper chest, keeping your elbow tucked at a 45-degree angle from your body.
- Lower the weight until you feel a deep stretch in the pectoral, ensuring your forearm remains vertical.
- Exhale and press the dumbbell back to the starting position by contracting your chest and triceps.
- Maintain a controlled tempo, taking 2-3 seconds to lower the weight and 1-2 seconds to press it back up.
Form checklist
- Keep both shoulder blades retracted and pressed firmly into the bench throughout the set.
- Avoid letting your torso rotate or your opposite shoulder lift off the bench.
- Keep your feet flat on the ground to maintain a stable base and prevent sliding.
- Ensure the wrist stays stacked directly over the elbow to protect the joint.
Pro tips
- Brace your core and squeeze your glutes aggressively to resist the rotational force of the unilateral load.
- Focus on driving your bicep toward the center of your chest at the top of the movement for a stronger peak contraction.
Make it harder
- Add a 2-second pause at the bottom of the movement to eliminate elastic recoil and increase time under tension.
- Slow the eccentric (lowering) phase to 4-5 seconds to maximize muscle fiber recruitment.
