WOW my muscles are so tired I need to sleep?
Muscle fatigue is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.
have a drink of water and then your muscles in you leg will get stronger And then you can do it every day.
Muscles need energy and oxygen to work. The energy comes from the food that you eat. We breathe in oxygen as part of the air, and our blood carrys it from our lungs to the rest of our body. Our muscles use the oxygen to realese energy.

When we exercise, our body sends extra oxygen to our mucles. Sometimes, when we exercise very hard, we need more oxygen than our body can get. This happens when our mucles are using oxygen faster than our blood can supply it. Thats when our muscles get tired.
