MyFitnessPal is a free service that lets you maintain a digital diary of your food choices, cardio work and strength training. When first using the program, you're prompted for such information as weight, height, age and activity level. You then enter what you're eating (and drinking) for breakfast, lunch and dinner, as well as snacks, throughout the day, and the app records the calories, fat, protein, carbs and vitamins.Or use your phone's camera to take a picture of a barcode and have the app look up the nutritional information for you. MyFitnessPal also lets you enter your workouts and strength training. Just as you do with food, you simply select the activity, push ups, sit ups, walking the dog, and riding x number of miles on a bike. Once you're done entering your information, you can look at charts, graphs and lists of your diet and exercise to get a better view of your day or week.
The amount of different workouts that can be found at your local gym or health center is reason enough to believe how much technology can help and improve fitness. New machines are made offering different styles of workouts that improve muscles you didn't even know you had, almost every year.
Plus, with new futuristic and architectual designs, gyms are just starting to look just plain cool as well.
