Our April issue features a bodybuilder who is more than just a bodybuilder—he's also a skydiver, bungee jumper, bull rider and anything else that gets his adrenaline spiking. Kyle Clarke is his name, and he uses his muscles for more than just flexing. Plus, we have the first excerpt from the best-selling e-book The Ultimate Mass Workout, a shoulder-shocking program from up-and-coming bodybuilder Armon Abidi, a complete kettlebell routine from Clark Bartram and answers about the science of bodybuilding from two top researchers.
