I recently read a trick when it comes to doing dumbbell bicep curls where you should face your palm upward and then when you slowly curl you bend your elbow and keep your elbow close to the body instead of away
I noticed that the gym a lot of people don't follow that. do you think they're making a mistake or do you think that they are doing it the correct way and I'm the one doing it wrong. I always thought that you should feel tension as well in your upper arm when you do the curl
