I do the courses here but am very much into the science of training all sports up to the highest level. I was reading Gymnastics How to Create Champions by Arkaev and Suchilin http://www.amazon.com/How-Create-Champions-Methodology-Gymnastics/dp/1841261416 if you want to see what the book looks like and since I am not in that world and Arkaev seems to use language used in the east it can be hard to dissect some parts. In the planning section on page 190. Workout 16 "The sixteenth part is devoted to developing the strength of specific muscle groups. For this we use strength training apparatus of the 'minigym' type with a weight of up to 50kg. He repeats the exercise 10 times" Has anyone read this book and know what he is talking about? I couldn't think if it was a ring trolley, its not the low rings because he talks about that in the next section with a weight belt, maybe a low pull-up bar with weight?. Any idea?
