Really want to give it 5 stars

I REALLY like this app, but everytime i make my own workout the app closes with an error.

Very good but...

This app is very good like the other reviews state, with great graphics and animation as well as a lot of exercises. However, it is missing a few core features and could use a few others. First is that it doesn’t have cardio exercises. So when you are looking at a your progress you only see calories burned for stretching or weight training. Second is that it doesn’t sync across devices. I own all three versions (laptop, iPad and iPhone) and each has to be setup separately and what you record on one doesn’t sync to the others. The other features that would be great to add would be the ability add (i.e. purchase) packages that center on specific types of machines. For example my gym has Star Trac exercise equipment which has some variations on the exercise machines already provided in the app. To improve accuracy and tracking of my workout, I would purchase those types of add-ons. Additionally, it would be great to be able to add comments to each exercise or routine. I’d like to note difficulty or machine setting (which isn’t always weight) or how a stretch felt which I could use in my next workout. Finally, the ability to sync with other apps that provide additional reports and graphs would be great. I also use Training Peaks and would love to see my exercises on their calendar and included in their graphs as well as seeing the exercises I do there in your app (especially for tracking weight, calories burned, etc.) Note that I love all of the great 3D4Medical apps, having purchased many of them. I just think this one could be improved from very good.

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.
