While there is no shortage of fitness apps in the iTunes marketplace, 3D4Medical’s iMuscle app aims to make it even easier to put together a customized workout. The app allows users to select muscles and muscle groups from a 3D model of the body, and shows a list of exercises to work out the selected muscles. Each exercise includes animations showing exactly how it should be performed, and individual exercises can be added to custom workouts.
From the product page:
To work on a particular body area, zoom into that area on the 3-Dimensional Muscle Man. Then choose a muscle to work on – a thumbnail list of all the exercises associated with that muscle will be shown. Then press on one of these thumbnail exercises and you will be shown an animated 3-Dimensional model performing that exercise. The primary and secondary muscles being exercised will also be highlighted. You can search for a particular muscle or exercise by selecting the appropriate tab in the Index function.
