Donny, the current one I am doing has shown such great results in increasing strength of punches, it is with reluctance I am looking to switch it up. Take a look at it, but realize I am using a home gym for the back stengthening ones, which I feel are largely responsible. Using the pull down bar for lats, close hand inward pull down, an wide hand outward pull down, plus pec deck. Not sure how this would translate to free weights tho.
