@tylerpath: Single arm dumbbell preacher curls are probably my favorite bicep exercise, but if you're low-key terrified of them, here's how to make sure you have a smooth and safe set: 1) adjust the seat height so that your armpit and upper arm are fully in contact with the pad. 2) use your non-working arm to pull yourself into the pad for better stability. #fyp #Fitness #gym #bodybuilding
