I think the most important thing for exercise is finding something that you love, and that you will keep doing long term because you enjoy it. I personally love to dance, so a Zumba type workout is great for me. I would do it everyday if I could...I'm always excited to go and it leaves me with a smile on my face. I have a few workout videos that I absolutely dread...because they are painful, or long, or boring. I know that I won't keep up with them long term.
