Keep trying different types of exercises until you find something that you enjoy! You may also find that either you do better working out with other people or that you prefer going it alone. Everyone is different and the trick is finding what works best for you!
For me, I love working out with others and having it on my schedule! I also love Zumba!!!! It's an even better workout as an instructor!!!!!! As an instructor, I have to make it to class and I have to practice in between classes and I have to do my best at class! It's fantastic!!!!!
