Fabulous! Fabulous! Fabulous!

I reviewed iMuscle prior to the update and although the review was generally positive, I lamented the absence of certain small muscles that are relevant to weight lifting. They are here as is so much more. The appearance of the model is cleaner and smoother. The rotation and zooming features are intuitive. The appearance of the program itself is polished and the lists of exercises will satisfy the novice and the experienced. Personal measurements and progress trackers are included. I don't use the social media features, but they are present for the interested. My only request (not really a complaint) would be the addition of trackpad pinch to zoom capability to a future version. I would also like a section labeling the muscular origins and insertions. The body mechanics of individual muscles is easier to follow when so labeled, I think. Overall, the program is great and the developer's responsiveness is evident.

Who is this for: workout enthusiasts, both novice and advanced, for ease of use and customization capability.
Who is this not for: someone looking for comprehensive anatomy including nerves and bony attachments. 3D 4 Medical offers separate programs for these.

Very good, very innovative app

I was looking for soemthing that would help me understand the muscular anatomy and what I’d be working with different weight-lifting exercises. iMuscle2 fit that requirement perfectly. While I have many resources for weight-lifting exercises, this app helps me keep straight in my head what body part I’m working with what exercise. I found that I was missing some from my workouts completely, like the rear deltoids.

The app itself functions well, and is easy to navigate. The only problem I’ve had is that the application locks up if I close my laptop lid and then re-open it while the app is on the screen. That may just be my particular configuration. I have a MacBook Pro summer 2012.

I’d recommend this app to anyone trying to get a handle on what exercises are for what muscle, and to better learn the muscular anatomy involved. Yes, it is not an encyclopedia of exercises for each bodypart, but the exercises provided are quite enough for starters. I’m very pleased with this inexpensive solution to my questions.

I absolutely love this app!

Being somewhat new to bodybuilding in my exercise routines, I have found that this program is exceptional in that it provides an opportunity to go through for instance if I am creating a workout for arms I can use the 3d model to select specific exercises that will work out each individual muscle allowing me the ability to make sure that my arm workout is all inclusive without missing a single muscle. I think this is awesome if you want to see more growth and definition in a specific muscle line in your physique locate that muscle on the 3d model and implement a bunch of exercises that will improve that specific muscle very powerful tool beautiful graphics user friendly great example clips to display proper workout motion 5 stars from me.
