The Vinsanity Six-Pack Shred system review & PDF free download. I’ve always stuck to a strict diet and worked out religiously; I hovered around 12 to 15 percent body fat. I’ve had decent abs for years, but I’ve never been able to get that perfectly cut look fitness models, athletes and actors have. I’ve always had a good diet and hit my abs hard, so it was so frustrating when I could never breakthrough and gain the six-packs you see on TV. Ten minutes into watching the Vinsanity Shred System I had several light bulb moments. I noticed how I had missed simple things were keeping me from an amazing six-pack. The three-pronged attack they give you is so easy to follow. If you do it you will be shredded – it’s really that simple! This is an incredibly efficient program.
