Getting your daily dose of healthy eating and exercise is a critical component of your success when  you're striving for wellness, and these online experts could be just the thing to steer you on the right path.

Tara Stiles
There's no doubt that yoga has taken off in popularity in recent years when it comes to body weight training. Tara Stiles, a yoga instructor whose YouTube videos have gained quite a following, focuses specifically on how this ancient practice can give you more energy and cultivate a svelte body. Her training expertise is perfect for beginners, as her approach is laid-back and fun, and she also narrows down which poses will work for your specific fitness needs and muscle groups.

Amanda Russell
Russell's cardio and toning plans work wonderfully for people who can't seem to find the hours in the day for exercise. Many of her videos on YouTube can be performed in 15 minutes or less. She also offers exercises based on themes, such as fitness moves for brides or finding ways to get arm muscles like celebrities.

Dr. Mehmet Oz
Made famous by Oprah, Dr. Oz has become a household name thanks to his popular daytime TV show. However, there is a wealth of wellness information on his website for you to explore as well, even if you don't have time for the tube. Many of the themes he focuses on are centered around healthy eating, all-natural anti-aging ideas and how diet and exercise can help prevent diseases.

Tone It Up
Karena Dawn and Katrina Hodgson are noted nutrition coaches and personal trainers who offer an all-around approach to staying fit with their website Toneitup.com. From recipes and nutrition programs to weekly schedules and fitness playlists, this site has it all. The two fitness gurus offer advice on fitness-related yoga moves, stretching, triathlon training and proper kettlebell use as well as toning routines for specific muscle groups like legs, abs and arms.

Tim Ferriss
Tim Ferriss' "4 Hour Body" tactics are controversial in some circles, but many people have found weight loss success with his advice and podcasts. Most of his ideas are geared toward "lifestyle design" and revolve around slow-carb dieting interspersed with occasional "cheat days."

Staying fit and healthy with a weight loss supplement or testosterone booster could be an excellent pairing with any of these online wellness programs.
