Different weights for same muscle?
Is it normal to be able to lift a higher weight amount on one machine at the gym and not be able to lift the same amount on another machine that is working the same muscle.. for example the chest. I noticed that when I am using a compound machine that targets Chest and tris I can lift 70lbs (3 sets of 10) but when I am using the pec fly machine, I struggle my sets at 60lbs... is this normal? Am I doing something wrong? Keep in mind I have been only doing this 3 weeks now.
