Hi, I don't have gym styles, but I do have B&G. I think the magic with that one is in the premixes. This will be my 4th time doing the workout, and each time it has been a completely different workout. I am using much heavier weights than what is shown on the video, for the most part. If you do that, I think you get a balance of endurance and strength as some of the exercises are very high rep. There is some plyo in there too. With all of the bonuses and premixes, I think B&G is a great purchase.
