Review by Dark1nvader

comm injuries - Excellent application. Easy to use graphical user interface. Deserves all the stars. But, adding a section talking about how to prevent most common bodybuilding related injuries would make this application one of a kind.

Version 1.1
Review by Kevinm78

Very poor port from iPad app - This is obviously not an app written for the Mac. It is an extremely lazy port from the iPad. It does not take advantage of a desktop computer's features and advantages. Here is my take: Pros: Main window can be expanded to take partial advantage of screen real estate. More than one (two) windows. Cons: - The layout does not take advantage of the larger screen size. Although there is a second window, it can not be resized - and it is small. During workouts the window is used to show sets and toggle with previous best. But since it can't be expanded, even just four sets requires a scroll bar. - Drop down menus in the windows are miniscule, showing only three choices at a time. This makes it extremely difficult to choose another option. There is absolutely no reason for this to be this way.There is room, even in this small window, to show over a dozen choices. - The app doesn't use the normal menus. There are only two options: the "iMuscle" (with the normal hide and quit options) menu and "Window" (which allows you to choose between the two windows.There are no choices to select the different features of the app. - Importing workouts from the iPad is buggy. It took a couple of attempts to get the correct workout to import. The first time a bizarre combination of exercises was imported. If you own the iPad version, unless you need a larger main window view, don't bother buying this version.

Review by The Ryan.

Cardio - So far the app looks great. One drawback—cardio is an important aspect of fitness. I do not see any cardio presets (e.g. sprints, running, treadmill, etc) in the software yet. If it is there, assistance finding and using is greatly appreciated.

Great App & Awesome Support - iMuscle 2 is a must-have app if you wish to get the most out of your workouts. Know what muscles you are working, so that you can get a balanced workout. All 3D4Medical apps are very informative, thorough, and user-friendly. Plus if you have a question, technical support is quick to respond. Most recently, Nicola N. & Jeff R. have been really helpful. Thanks 3D4Medical for great products & the best team!

Review by GotanFreak

Great App - I’m not a doctor or physical trainer but being able to target the muscle that is giving you problems and then going to your therapist with an intelligent question…that makes it worth all the money and more. Also, when I’m running and want to target a certain muscle group this app really helps. I’ve been running competitively for 25 years and I wish i had this when I first started.

Review by Doconwheels!

Well worth the investment! - I've been using this app for years and since its original release the developers have updated regularly with new content and features. I never had to pay for an upgrade and the content they add is probably worth a few $$$. I sync data between my iDevices all the time. Best fitness app available on the app store.
