During a punch, your fist is looked as an extension of what part of your body? a. head b. arm c. hip d. foot

B. Arm because why would it be head or hip or fit if your fist is literally connected to your arm lol

Your fist is an extension of your arm because your hand is connected to your arm.
I hope this helped! :-)

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.
