I know someone who is autistic and is 20 years old. it's been years and I noticed that he is becoming more aggressive and aggressive. he can get very sensitive and angry. He wasn't like that when he was younger. is this normal for an autistic adult?​

Although it isn’t very common, it’s is normal. Most people with autism will be the most aggressive and sensitive when they are young and get calmer as they age. But there have been some studies where people with autism either get worse as they age or stay the same.

Well if you pick a machine to work on and that's gonna be your exercise if you don't stick to that machine your muscle strength your muscle mass rather will change because you haven't been doing it you change something in your exercise routine which changes your body's form of dealing with things for example you might become weaker or stronger depending on what kind of exercises you do in whether or not the machine you picked actually your muscles grow.

Maximal strength i believe
