There is the video where 6'9'', 400-pound Icelandic strongman Hafthor Julius Bjornsson toyed with the 5'9" UFC star in a training session in Ireland before Conor's big fight against Jose Aldo. Hafthor talked about the throwdown and said he went easy because, "If I would push all my power into him, I would crush him. Crush him. I had to hold myself back because I have too much power for a man his size."
