A good weight for a lat pulldown would differ from person to person. If you’re new to performing the lat pulldown, start with a light weight and focus on learning good technique. Once you’ve learned how to execute a lat pulldown with good form, you can add more load to a manageable weight that challenges you but also doesn’t compromise your form. As you perform these consistently week over week, you will find your body will get stronger, and you can adjust the weight if needed.
