It'd be easy to blame it on Tensai. A REAL powerhouse like Goldberg or Lesnar would have got Tensai up with ease regardless, especially after two attempts, and this isn't the first Ryback strength fail. He's big but he's nowhere near as naturally powerful as a Goldberg or Lesnar.
Naturally powerful? Why don't you stick to what you know here, which is clearly not power lifting/bodybuilding/fitness in general? Just don't embarrass yourself. Goldberg and Lesnar were both very involved in power demanding sports from a very
young age. Both football and Greco Roman wrestling require very demanding strength training routines, which then lead into bodybuilding, which then lead into power lifting. Ryback is a guy who popped steroids earlier in his career and got himself in rehab because of it. Do the math.
