I have working with The Cube for the past 2-3 weeks now. I love the changes in strength that I have been seeing so far but my joints are starting to give me some issues. I was wondering if the moving the heavy weight every day could be causing me some joint pain. What I had thought about doing is going through 1 cycle of The Cube then doing something like a GVT Upper/Lower split for 3 weeks. Was looking at alternating them but did not know how doing GVT for 3 weeks if that would kill my strength gains from The Cube. Any help you can give me would be greatly appreciated.
