HOW TO DO SINGLE ARM DUMBBELL PREACHER CURL
- Set the preacher bench so your armpit rests near the top edge and your working upper arm is fully supported.
- Hold one dumbbell with an underhand grip and begin with the elbow almost straight, not forcefully locked.
- Curl toward your shoulder without lifting the arm from the pad, then lower slowly through a range you can control.
- Keep your wrist stacked and your chest steady instead of twisting toward the weight.
