Extra weight it hurt knees hurt because heavy things are hard to carry. When you weigh more your knees have to hold up all that weight every time you take a step just like carrying too many books makes your arms tired.
Knees break easier than other parts of your body because they can only bend one way like opening and closing a book. Inside your knees is soft stuff that gets worn out when you use it too much and it cannot grow back like when you get a cut.
You know when too much weight is hurting your knees because they feel stiff like rusty door hinges in the morning. Walking up steps becomes hard work and your knees might feel warm or look bigger than usual after you walk around a lot.

Sitting Too Much and Weak Muscles Around the Joints

Sitting all day makes your leg muscles weak because they do not get to move . When your leg muscles are weak your poor knees have to do all the work by themselves which can make them very tired.
When you stand up, you feel shaky and going down steps feels scary because your knees don't feel strong.
Easy moves you can do at home to help are standing up and sitting down from your chair lots of times. Walk around your house when you talk on the phone. Jump up and down during TV shows or walk in place.

Sports Injuries Like ACL or Meniscus Tears

When you keep playing sports with sore knees you make them hurt much worse and knees get more broken when you do not let them rest.

You know if you are hurting your knees too much when they hurt all day long even when you are sitting down. Your knees feel tight every morning when you wake up and walking up steps becomes hard and scary.
