The EZ Barbell Preacher Curl is excellent for isolating the biceps. To avoid common mistakes, ensure your elbows remain stationary to prevent shoulder involvement. Use a full range of motion without locking out at the bottom to maintain tension. Beginners should start with lighter weights to master form. For more advanced lifters, slow the eccentric phase to enhance muscle engagement. Adjust the bench height so your upper arms rest comfortably and ensure a firm grip to minimize wrist strain. This exercise can be adapted by using dumbbells for unilateral training or resistance bands for varied tension.
