I have just started to offer online training as an option.
I plan to instruct people in the MELT techniques and think of instances when people do not have access to a trained instructor and are wrestling with getting the techniques by using the book or the DVD. While hands-on is still me preferred way of training, an online class is still a great option for people who otherwise cannot get any instruction at all.
Other than that, I may include online training for existing clients. One of them recently had to move away , and she is a candidate for online personal training because I know her well.
