I think online personal training can be a great tool. I’ve recently created http://biomechanicallyfit.com/, which I offer two package options individuals can choose from. I offer 100’s of exercises and workouts they can view and follow if they would like. I also use gotomeeting to connect with clients throughout the month. Quality will never be the exact same since you won’t have that in person one on one feel but you can’t have everything especially at a lower cost.
