Well-Known And Appreciated by Bodybuilders

Whether it's maxed effort squats, deadlifts until your hands bleed, 50 rep pullup volume, or blasting arms until they turn into a Rand McNally map, why would you choose anything else?

It’s certainly not for everyone because not everyone trains all out of the maximum effort. Not everyone is willing to do the work – day in and day out. Not everyone is fully committed. Not everyone still hits the iron hard even if they “don’t feel like it” or “something comes up.” You either truly want it or don’t, plain and simple. You know what they say – excuses are like, you know what – everybody’s got one. Excuses or results, your choice – which one are you going to pick?

Those who know Jack3d know that you must put in the blood, sweat, and tears at the gym if you want the results. There are no shortcuts!​
