What muscles does the preacher curl work?
The preacher curl works the biceps muscles. The biceps are comprised of two heads: the inner head and the outer head. The preacher curl primarily works the outer head of the biceps. The bicep muscles have multiple functions. They are responsible for flexing the elbow, which is what we do when we perform a curl. They also help to supinate the forearm, which means turning the palm from facing down to up.
The preacher curl is different than other bicep exercises because it is an isolation exercise. This means that it only works for one muscle group, in this case, the biceps. Other exercises, like the chin-up, exercise multiple muscle groups at once. The preacher curl is a great exercise to add size and strength to your biceps.
How do you perform the preacher curl?
There are a few things you need to keep in mind when performing the preacher curl. First, start with a lightweight. You can always increase your weight as you get stronger. Second, keep your back straight and your core engaged. This will help you maintain good form and avoid injury. Third, focus on keeping your elbows stationary and curling the weight up. Lastly, squeeze your biceps at the top of the curl for maximum muscle growth.
Common Mistakes
One of the most common mistakes people make when doing the preacher curl is swinging the weight. This takes away from the isolation of the exercise and puts unnecessary stress on your joints. Another mistake is not curling the weight up. Be sure to curl the weight until your biceps are fully contracted. Lastly, some people use too much weight and sacrifice form. Remember to start light and focus on good form before increasing the weight.
Preacher Curl Variations
There are a few variations of the preacher curl you can do to target different muscle groups.
