Dream about being exercise is an indication for falsehood and deceit. Perhaps you are pretending to be someone that you are not in order to fit in. You are seeking validation and acknowledgement for your achievements. Your dream is a sign for some dirty situation. You are just going along with what everyone else is doing.
Being exercise points to the point where the conscious mind meets the subconscious
Something or someone is draining your emotionally. You need to be more open or friendly. Your dream points to hidden areas of the conscious mind and different aspects of your personality. You need to learn to let go and look toward what is ahead for you.
