Teen's sleep cycles change when they hit puberty, so many teens don't feel sleepy until 11pm or later. There are ways to re-set the cycle, do a Google search on "teenage sleep cycle research" and you'll find lots of info.
I have to be at work at 5:30am, so I go to bed around 8:45 and get up a 4:00. This is not what my body wants to do (it's still dark at 5:30 even in the summer!) but I've gotten used to the schedule. What helps is not sleeping in on my days off... which isn't always easy!
But even when I started work at a more reasonable hour, I never did have an easy time of working out in the morning. People, adults and teens, have different times of the day when they have the most energy. If I tried to work out shortly after I wake up, I'd end up hurting myself, or at least not being able to put my full efforts into my workout! I perform best right after I get off work (3:30pm).
Have you tried working out later in the day, maybe after you get out of class for the day? Would your parents be agreeable to letting you experiment and see if that works better for you? Keep in mind that if you work out too close to when you want to go to sleep, it can keep you awake. Finish your workout at least two hours before bed and you shouldn't have any problems.
And if you need to sway your parents to your side, you'll need to be sure that you actually DO your workout on the scheduled days at more-or-less the same time each day. It's best to have a regular schedule, anyway... and research also shows that you remember what you study the best if you do it shortly before you go to sleep. So work out after class, and study before bed!
You make your choices, and you live with them. In the end, you are those choices.
