Mobile FitDeck is essentially a virtual deck of cards with different exercises explained on them. The exercises are all ones you can do without equipment - all you need is your mobile!
Mobile FitDeck works simply by offering you a series of exercises - you can choose random ones or have them grouped by muscle groups. Each exercise is explained with a diagram and there are recommended times or numbers for different abilities. Clicking right takes you to the next exercise, and after a round of activities it will give you a scheduled rest and water break.
Mobile FitDeck features a great range of exercises, and the fitness programs are well put together. Unfortunately it features no way to record your progress, so you have to rely on personal honesty!
If you want a good idea of a well rounded exercise routine, this three day trial od Mobile FitDeck is a good place to start. The developers say that it's designed to be simple to use, which is why it doesn't ask you to create your own routines. There's something in that idea, as Mobile FitDeck doesn't make fitness complicated.
If you're looking for a set of simple instructions to get you fitter, Mobile FitDeck is a neat app for your phone to get you started.
