Yes, “there’s an app for that.” Some provide the most important element – FUN! They can be rewarding, literally rewarding. I’m talking about real cash and prizes. Whether you’re just getting started or feel the need to accomplish more, a great software application can give you an edge to achieve your fitness goals. Many integrate social networking, which adds encouragement, competition and the chance to make new friends. Cost and convenience are primary reasons for the growing popularity of exercise and fitness apps.

They’re significantly cheaper than gym memberships and personal trainers, and these fitness apps perfectly fit your schedule and demands because you’re in full control. So take control and wield it as any skilled craftsman would a prize tool.

Use caution

I reviewed a few below, but there are some things to remember. The fitness app doesn’t do the work for you. In our modern society, we need to add it to the list — no perfect exercise, no miracle pill, no magic diet, no special app. Living life takes effort, and you must take ownership of your actions, or lack thereof. Many provide detailed instructions with adequate audio and visual aids, but this is not a substitute for a trained and experienced teacher. There is the potential for injury and be certain you are medically approved to attempt the program. Take the time to learn, listen to your body, and solicit qualified advice if you’re unsure.
