i work out at the gym in the mornings,
If you are working out in the mornings hard enough you should be too tired to even think about doing anything else the rest of the day.
However, if you simply CAN'T stay off the Body Machine or whatever it is called, why not put that time on it to the best use you can?
Target a week muscle like the rear delts, or the side delts, or the bicep brach.
SMALL muscles that are lagging and do not require compound movements for direct stimulation.
Spend time on it with a light weight doing nothing but mastering the mind and muscle connection that few people fail to grasp. Feel how YOUR muscles move, contract, stretch and the point of where the tension shifts from one muscle to another. Master this and then apply it to your workouts in the gym. Experiment with different angles and limb positioning.
Find a way to use the way to help you incorporate fascia stretching whether it be through continuous static holds in the stretched position or forcibly elongating the muscle through tension.
Simply jumping on it and going isn't going to be overly productive. There are better ways to work off the extra energy you may have. Hobbies, fixing up your house, yoga (laugh if you want, but you can directly enhance your muscle shape and size this way), sex (no complaints here) or simply doing all the things you want NOW that you won't be able to do when your job starts in a month and half.
What kind of job are you starting now?
