It sounds like you have hit a wall and need to change things up. When you do something routinely your body can get use to it and will stop showing results. Maybe you should try working out every other day. One day focus on just the upper body and then the next time focus on lower body. Also, using wieghts or resistance bands will increase your metabolism. Make sure you are drinking lots of water each day to....very important.
What is your diet? Make sure that you do not go over 2 fruit servings a day. Fruit contains sugars, good sugars, but sugars nonetheless. I learned that after gaining weight. Thought that I was doing right by eating lots fruits and veggies. You can eat endless amounts of greens but limited amounts of yellows. One more tip, sip on ice water throughout your day. It will increase your blood flow which raises your metabolism.
Anyway, hope this helps!
I agree that once your body gets used to the same routine, you will have a hard time losing weight. You need to change it around regularly to keep your body "off guard" so your exercising will again be challenging.
Your diet is very important as well. I don't necessarily agree with the only 2 servings of fruit. I will say that it's much better to eat whole fruit than to drink fruit juice because with the whole fruit, you get the benefit of the fiber and vitamins and minerals that often "hide" just below (or even in) the skin or peeling. When you drink juice, you get the calories but not the other benefits.
You could aim for higher protein and complex carbs, as that will fill you up more quickly and help you stay fuller long. Also make sure you an adequate number of low/no fat dairy and some "good" fats, such as those found in avocados, nuts, olive oil, etc.
And don't forget to change things around -- both exercise and food.
