The personalized element of personal training is retained in this type of online training, but the difference is this method is that the trainer does not work with the client in-person. The obvious way to boost your cash flow is to increase your client base. Creating online training service offerings that help people achieve their fitness and health goals, but do not require a ton of time, allow you to gain back that ever so important personal and financial freedom. Landing a job in the fitness industry is exciting and rewarding. Regardless of the direction one goes, maximizing earning potential involves spending a little money up front in order to get a bigger return. You get a group of people together, charge them something small like 5 or 10 pounds for 45 minutes and work your group to hell. This type of online training requires zero client interaction, but strong online marketing to help drive attention to the program and convince clients to make purchases.
