Muscle ache is normal...

Waking up in the morning, you shouldn't at all be unduly tired, if you are, lack of sleep could be the factor. However, your muscles can tire and muscle ache can occur when you overdo any physical activity, that's normal. How long you will last before getting tired while performing the task depends on the energy you have. You need energy, your cells need energy and the less energy you have in your body, the lower will be your physical work capacity. Hence, the supply chain model for your body must be in place and you know best how your own body works, all I want to say is, feed your body with the right nutrients...the right food in the right proportion at the right time.
However, if it causes you pain or soreness in any areas of your joints while lifting something, then it may need some attention. The bottom line is give your body physical work activities on a regular basis. Either in the form of exercise in the gym or outdoors or the normal house chores, they will do you a lot of good.
