!!!Skeletal Muscle Contraction!!! (skeletal muscle physiology) SCIENCE EXPERIMENT

Crazy Chris shows you how to put your muscles to the test with a nifty science trick!

Objective: To understand how our muscles move by contraction only.

Materials Needed:
- Your Arm
- Somthing To Push & Pull

Step 1) Relax your arm and feel both of your muscles.
Step 2) Pull on something like pushing up under a desk and feel both of your muscles.
Step 3) Push on something like pushing down on top of the desk and feel both or you muscles agan.

How It Works:
Mucles are just too weak to be able to expand with enough force so they can only contract. This is why when you push on something the tricept muscle feels tough and when you pull on something the bicept mucle feels tough.

  • that's why they seprate arm workouts with bicep curls and push cable tricep manuver.

  • @mynameisradar that right because skeletal muscles can only contract :D

  • Great video 5* =)

  • Thanks again. Im glad that you allow me the privlliage to continue entertaining and sharing knowledge with you each week. =^D
