STANDING DB PREACHER CURL
- Set a bench either to an upright angle or as close as you can get, and stand behind it. Most people get this exercise wrong by opting for a 45* angle, which won’t provide enough gravitational resistance.
- Take a dumbbell in your hand and place your elbow at the top of the bench.
- Control the weight as you extend your arm fully, then curl it back up by squeezing your biceps hard.
