He said leading to that Brock fight he only cuts small weight to make the scale.. so something like 10 lbs for a HW is not something to serious like legit skip the night meal, don't eat breakfast, go toilet and just sweat a little bit half ass of a workout and the weight should be off.. then you drink and eat up and recover your size.
Reem vs Brock was 263 lbs with jeans on and he said he did that small cut to be right at the scale.
It's real easy for a HW to over cut especially if he only cuts so little.
Now this is him in K1 where he has no grappling so he can enjoy the size even better hence why he is a tad heavier then in MMA even in his Uber days.
Then look at pictures from K1 you can see he is a tad bigger:
Even in his UBER form I see him:
I see him the biggest in his K1 fights.. around 280-285 lbs would be my guess.
And a tad smaller for when he shows up for his MMA fights.. around 270-275 lbs.
Of course I wasn't there with a scale on fight night to put him on and see 100% I'm just going from the pictures and from what he said, for his MMA fights he had to cut a little bit of weight that's it.
For all we know he could very well be under the 265 limit and he just played it up for the size factor and to get more buys out of UFC 141 vs Brock.
