Should I lift weights or do aerobics first?

or

The answer to this question depends on what your goals are. If gaining muscle is your main concern than you should lift weights first while you are full of energy. You don’t want to get tired doing aerobics and not be able to give your workout your all. If you want to build stamina and endurance you should do aerobics first. You may want to consider doing aerobics on the days when you are not weight lifting.

Be careful not to overtrain by working out every day of the week. Taking a day off once in a while is good for the body also.
