Can't afford a personal trainer? Fitness Buddy will be the best dollar you've ever spent, with more than 1700 exercises in its database.
Fitocracy takes the drudgery out of exercise by turning it into a game. You can undertake quests, unlock achievements, and ''level up'' with the points you earn after every physical exertion. You can also join groups of like-minded individuals to chat about exercise and compete on the leader board. The only downside is that the wealth of features makes the app difficult to navigate.

MyFitnessPal makes counting calories as painless as possible thanks to its extensive database of more than 2 million food items, including many Australian brands. It tells you how many calories you can eat a day (based on your personal statistics and goal weight), and you can log your exercise to make the calorie tracking more accurate.
Despite its name, RunKeeper covers the full gamut of aerobic activity, including mountain biking, cross-country skiing, swimming and rowing. It can take advantage of your smartphone's GPS to track your progress on a map if you're outdoors, but it works equally well for indoor workouts at the gym, especially if you pair it with a compatible heart-rate monitor.
Running is a great, low-cost way to get fit, but it can be hard to break into if you've never done it before. Get Running uses the popular ''Couch to 5k'' running program that gradually has you running five kilometres (or for 30 straight minutes) in nine weeks. The first week has you alternating walking for one minute and running for 90 seconds for half an hour.

There are dozens of custom workouts that target different areas of the body, and each exercise includes detailed descriptions and photos (along with HD videos for a select few).
