Anyone help me to get Joomla Fitness Template

Hi Experts,
A friend of mine is running a fitness club. I have been assigned a duty to develop a website for his business. As I am not that expert to develop a high profile website and manage it. I have decided to use Joomla Fitness Template. Can anyone tell me what are the advantages and disadvantages of Joomla. Is it easy to use or I would require to have training?
