Extremely hyper toddler

My 19 month old is extremely hyper to the point where we go to activities and he just runs off or goes up to all the kids and parents and just stares at them, sometimes he will try hit them or he hands them things. He then grabs toys/ teachers equipment and throws it all over the place. He cant sit still and watch the educator at all. He goes to these classes where there is a circuit they have to work their way through and he just picks up the cones etc and will throw them all over the place. Its so exhausting and peoplr have mentiomed that he isnt well behaved. I dont know what im doing wrong. I dont want to hit him and it hurts me if i do time out as he cries. I just say "gentle hands" and show him how to be gentle etc but then he will be gentle then grab my hair or something and pull really hard while laughing. I feel at a loss. Has anyone else experienced this? Other kids his age all seem to be alot calmer and don't run away or cause as much chaos. I always end up talking to educators at the activities we do because they come up to me to mention how "social and energetic" he is. I feel they are trying to word it nicely. Am I doing something wrong? Has anyone else experienced such an intense toddler?
