You are tired because you run out of glycogen mid-workout. Load up on carbs an hour before you exercise, get that glucose pumping though you. This is the one place creating may help you, or you could just eat more before a workout, or even drink fruit juice during your workout, you will have more glycogen stores. You are yawning because you are not breathing properly, 2 different issues.
