Keep in mind that he is only 11 weeks old and full of energy. Now is the time to start obedience training, but be patient. In addition to saying "no," redirect him to a correct behavior. Get him to play with a toy for instance. Make sure he has enough exercise and a good schedule for basic activities during the day. If you do things at about the same time each day, your pup will naturally fall into the routine.
Puppies get zoomies a lot. They zoom around the room and may bark and appear to act aggressive. More often than not, the behavior is actually playful. Stay calm and don't show any excitement or frustration. Any negative energy will just fuel his excitement and get him going more. When Max would do this, I would very lightheartedly say, "Oh, my feisty boy." Being gentle and nonchalant is completely disarming.
I would recommend not holding him down. You can calm him down faster and in a much less stressful way by sitting motionless on the floor. Don't move a muscle until he calms and comes to you. When he does, gently say, "good boy" and give him a small treat. I promise this exercise will train him to calm down and come to you. You can then introduce command phrases and words, "settle down" or "come" and "sit."
You can also ignore him when he is acting out. Withdrawing attention is very effective.
