It's about to go Beast Mode in Finland ... where Marshawn Lynch and Gary Barnidge are gearing up to run a female tackle football camp ... TMZ Sports has learned.
Turns out, women's football is EXPLODING in the Nordic country -- they've already got a whole bunch of female full contact pro teams ... and now, they're getting NFL guidance.
It's all part of the American Football Without Barriers foundation and Barnidge -- Cleveland Browns tight end -- says this will be the first time they'll have a women's only camp as part of the program.
