      Improving muscle strength (non-statutory)

      Lesson details

      Learning outcome

      I can design a fitness circuit to improve muscle strength.

      Key learning points

      1. Muscles that are found close together on your body often help you to perform similar movements.
      2. Athletes focus their training on different muscles depending on their sport .
      3. Humans can improve the strength of their muscles through exercise, such as lifting weights.
      4. A complete fitness circuit should aim to improve the strength of different muscles in the body.

      Keywords

      • Muscles - Muscles are parts of the body which pull, causing bones to move.

      • Athlete - An athlete is a person who is good at sports or physical exercise, especially one who competes in organised events.

      • Exercises - Exercises involve using effort to move our bodies so that they are fit and healthy.

      • Fitness circuit - A fitness circuit is a type of workout that involves doing exercises that target different groups of muscles.

      • Stretches - Stretches are when you extend your body, or a part of your body, in order to stretch your muscles.

      Common misconception

      May believe that if you have small, weak muscles you can’t make them bigger and stronger.

      Show the children that through using certain exercises most people can make their muscles stronger.

      Teacher tip

      Be aware of different body shape and sizes. Celebrate body diversity and use examples of people that have lean muscles which are just as strong as those with big muscles. It is a good idea to perform a class warm up first in task B.
