Targeted both for professional teachers and people who want to train at home, Turnstep.com is the way to go if you want to get hold of a huge variety of steps aerobic workout routines. Granted that the site isn’t at all attractive in terms of design; still, the information is not only plenty, useful and free, but it’s unbelievably easy to understand. The site presents some new set of moves for specific exercises or whole classes several times a week, plus you can subscribe to RSS feeds to learn whenever a new one has been published, and also a glossary explaining what each move consists of with an animated gif where you can see the moves being done. One of my favorite things about Turnstep.com is that users can also get varied routines for ‘Adaptative Aerobics’, which is the kind of exercise people with disabilities can practice. There’s even more, though, like the medical information on the benefits of step aerobics routines or the library of reviews of workout tapes in every style you can possibly think of: cycling, aquatic, personal trainers, yoga, pilates, etc. Also interesting are the bulletin boards, which you can join to discuss the more business-like aspect of aerobics and being an instructor.
