Lesnar can lift a sandbagging Tensai, argument is silly. You can say Lesnar can lift 1000lb with 1 hand, he'd still struggle to lift a sandbagged Tensai. Why you ask? Because if you're expecting a slight jump to help you lift him up, that's what you're set for. If you're not expecting to lift that much weight then you won't.
When benching etc you are prepared knowing what you have to lift. If you lift a wrestler you expect to leap slightly and doesn't. You aren't prepared for the extra weight you need to lift, extra strength needed to lift, as well as how much legs, knees, and back etc to put into it.
