The best yoga certification program is one that truly offers a wide range of areas and can suit the needs of everyone involved. As a yoga instructor, you won't know if you're going to be teaching a class room full of strength training sports enthusiasts, or complete beginners. Because of this uncertainty, you need to be able to lead a class that caters to all levels, and then also turn up the intensity when the time is appropriate.
However the best instructors didn't always learn from the best yoga certification program. Some of them began on their own, learning how their own bodies worked and then went from there. Obviously it is difficult to teach other people how to be more comfortable and aware of their own bodies if you aren't that with yours.
There are many yoga certifications out there and not all of them are very good. You want to make sure you spend some time and do your research. You don't want to learn how to teach yoga, only to find out later that you are in fact endangering your students with subpar yoga instruction. The best yoga certification program will be one that also emphasizes being humble and knowing when you are wrong. This is a trait that 'the best' instructors and the best people in general will have. We all have our faults and we can only improve once we realize and accept what those faults are.
Since there are many different types and levels of yoga, it is also very difficult to define one certification as the actual best yoga certification program. A pre-natal yoga program or a harsh, heat intense yoga stretch program are two completely different animals. Some classes are just not very appropriate for some people. So while a deep breathing, slow moving class may be just right for one person, another person might actually hate it. They would definitely have different opinions on which school offered the best yoga certification program.
These certification programs often require a substantial commitment in the form of instruction hours and also live teaching sessions. Depending on the school, students must also learn Sanskrit, an ancient Indian language in order to fully understand the ancient yoga teachings. If a school claims to be the best yoga certification program and they seem to follow a traditional form of yoga, you can be sure that they'll probably require that you learn Sanskrit.
Many people who were once only into aerobics or lifting weights, now also incorporate a healthy yoga regimen into their workout schedules. Flexibility is very important to any healthy body and especially for people who lift weights. Weight lifters often lose a lot of flexibility when gaining muscle, so yoga is a great way to maintain or gain back some of that lost flexibility.
In fact, so many people have taken to becoming yoga instructors that now even regular personal trainer certification programs offer yoga certification programs. Organizations such as ACE and the AFAA, who are the leading certification bodies in the personal training industry now have full fledge yoga programs. However, finding the best yoga certification program for you is often a personal choice and you should definitely do research before committing your time and money to any organization.
