Tips: Millions of trainers rep away on the sloped side of preacher benches all over the world, not knowing that a better exercise is just 180 degrees away. By turning the pad around and performing spider curls on the straight-edged side of the bench, you get almost twice the range of motion. Spider curls allow you to lower the bar all the way to the bottom of the movement, giving you a stretch that will equate to more productive reps. Seeing as just about everyone wants bigger biceps, spider curls deserve to bump preacher curls off the list of ???mandatory??? arm exercises.
Anyone ever try these?
