“John Grubes book is a masterpiece, or the most under rated book on the market wildman training is one of the most advance training systems I’ve experienced.
The routines in The SuperStrength Playground manual are cut and dry, no guessing, no theories, only the truth. I highly recommend the training for anyone who really wants to get results. Bring your lunch and your A game.”
