I have tried both fitness blender and the nike training club app and prefer the app. But it could be based on how I workout. I workout at 6 am in my bedroom so I don't wake anyone else up. The app is so concise and bullet proof and I like that the training is very no-nonsense. There is no conversation or filler. It is all just exercises using a timer that both has a beep and a bar that goes across my phone. I feel like not only are the workouts very good but the structure just WORKS on a phone.
