Machine Preacher Curl

Preacher Curls using machine are a great exercise to isolate your biceps and build strength and size. Here are the steps to perform them correctly:

1. Adjust the seat height and the lever arm so that your upper arms are resting comfortably on the pad and your elbows are aligned with the pivot point of the machine.
2. Grab the handles with an underhand grip and keep your wrists straight.
3. Curl the handles up towards your shoulders, squeezing your biceps at the top of the movement.
4. Slowly lower the handles back to the starting position, keeping tension on your biceps throughout the range of motion.
5. Repeat for the desired number of reps and sets.
