Regardless of who popularized the method, it has been used in German speaking countries for years as a training method used in the off season to help lifters build some lean muscle. The weight will seem light at first, but once you get a few sets in, you will start to fatigue; especially if you aren’t used to a high volume routine. If you plan on doing a cycle of GVT, plan it around a bulk and do it for a 4-6 week cycle, and then go to a lower volume routine for a several weeks while you recover.
