In my opinion the health and fitness niche is probably the biggest and most profitable of them all.
Yes it is competitive as well but don't worry too much about the competition.
The market is so big that there is more than enough money for everyone.
If you look at the highest priced Amazon sites on Empire Flippers then you will see that most of them are in health and fitness.
It is an awesome niche to be in and Mike Mckay's new Fitness PLR pack can make your life a lot easier.
You can use the product review videos, articles, and reports in the package on your own sites.
Just make sure you redo them a bit to make them somewhat unique.
I usually create a new title for the Ebooks and also a new cover. Then I would add some unique content to the book and then sell it as my own or give it away as a lead magnet on my sites.
The videos can be uploaded as is to all the video sharing sites and also your own site. Just change the titles.
Anyways, I think it is worth grabbing some good PLR content to use on your health sites.
