A slipped or herniated disk is likely to happen due to the strain on the back. This can occur during heavy lifting and older people tend to have a higher risk of injury. The pain associated with a slipped disk usually goes away within six weeks.

2. Regular walking

You must do these exercises 3 or 4 times per week, provided they do not cause or increase pain. You can also do yoga and tai chi. Always discuss the suitability of these exercises with your doctor and learn from an expert.

4. Sunshine


Vitamin D deficiency is associated with muscle weakness according to a 2002 study published in the American Society for Clinical Nutrition journal.

Simply expose your legs to the early morning sunlight for 10 – 15 minutes daily.

It is always important to remember that you should consult with your doctor before beginning any at home treatment. If you believe that your weakness in legs is being caused by something more serious, seek medical attention immediately.
