1. Spider Curls
Begin this exercise by putting the bar on the sitting part of the preacher bench. Make sure it’s balanced so it doesn’t fall off. Then, step to the forward part of the bench, where you would usually put your arms and lay on your stomach at 45 degrees against the front side of the bench. Your feet and more importantly your toes, have to be well positioned on the floor and your upper arms need to be on top of the inside pad on the preacher bench. Then, take the barbell or dumbbells while holding a supinated grip with your palms upwards. Your arms should be about as wide as your shoulders or a bit closer, but never wider. Lift and exhale, hold for a second and squeeze your biceps, after which you should bring the bar or dumbbells down, while breathing in. Do 4 sets of spider curls, with 12, 8, 6 and 15 reps each, respectively.
