The number one thing that a coach needs to deliver is your personalized fitness program to follow. A great online fitness coach is going to give you a completely customized workout program that is based on your goals, needs, and experience. If your program isn't custom, don't buy it from a coach. Don't settle for some $19.99 one-size-fits-all garbage that you could easily find for free online!
While not all personal trainers are qualified to discuss nutrition with their clients, some do have certification in Sports Nutrition, Fitness Nutrition, or even a full out Nutrition degree. A complete program from your coach should include nutrition guidance throughout. Don't limit your results because you are confounded by nutrition. Everybody involved in fitness knows that your diet is even more important than a great training program.
If you are not talking to your online fitness coach on a weekly basis, you should find a different coach. Basically, it is a great thing to be bugging your coach regularly to learn as much about health, fitness, and nutrition as possible! You should be picking a service that allows email contact between you and your coach regularly. Weekly emails for support and guidance are a minimum. Even better would be a service that allows you, the client, to contact your trainer whenever you need help!
If you want results, an online fitness coach is a great start! Pay a low price, get great results, and enjoy your freedom of scheduling – unlike a local trainer. Don't forget to compare coaches and pick the one that fits you best. Do settle for the cheapest service, or the most expensive service for that matter. Get your coach and get working towards your goals!
