Alternative Exercises Standing Dumbbell Curl, Standing Barbell Curl, Cable Curl 2 Comments Michelle says: April 7, 2021 at 7:41 am What’s the reason on kneeling? My knees kill when trying this, so I just stood up. Then which is better dumbbell or barbell? Or should I alternate?

Feel free to stand if it hurts your knees or place a mat underneath them Log in to reply Leave a Reply Click here to cancel reply. You must be logged in to post a comment.
