Missing some vital functionality

Good app, but I am missing the overall calories, strength overview…
Also it would be great if there were some game-center compatibility to challenge some friends…
Filtering the equipment - would be better if you could select a couple of options, not just one, when you create your own exercises… Also an assesment whether it would be a difficult or easy would be nice...
Last but not least I miss the sync of data with iPhone/Ipad app…
p.s. really hate it what I have to reset the LB/KG measurments all the time… would be nice if it would be on a system scale...

cool but doesn’t fit my needs

it’s beautiful to look at and the explanations and visual references for the exercises are clear. However, I was interested in their preset weightlifting workouts to diversify my existing routine. A KEY missing ingredient: you cannot specify what equipment is involved in the chosen exercises. My apartment buiding has a small gym with dumbbells and a bench but not barbells or some of the machines listed. I wish I could have the app create a full-body workout routine for me using all the equipment at my disposal. I do believe there is at least one routine that’s designed for bodyweight only exercises, but that’s not what I’m looking for either.

iMuscle 2 is a fantastic app!

This truly is the best workout app available! Having the ability to use the 3D model to select muscles is outstanding. It's a great way to learn about your muscles too. The animations are extremely helpful too in that they explain how to perform each exercise. I've used many workout apps in the past, but this one has to be the best. I have recommended to all my family and friends.
