You owe it yourself to experience the most uniquely effective upper body strength system in existence due to its superiority in building muscle, strength gains, core training, improved joint health and stability, functional shoulder mobility, and firing your metabolism for weight loss and general health improvement. LOOK LIKE A STALLION… FUNCTION LIKE A MULE. Become muscled and sleekly cut like a stallion. But preferring only steady terrain and less heavy loads, horses take a backseat to mules, who are stronger, can better handle heavy loads, and better negotiate difficult terrain. Grind out those pushups on the Twisted Mule and you will see a stallion in the mirror while possessing, on the inside, the optimum functionality of the mule.
