In the latest edition of Myles Garrett's unreal gym feats ... here's the Cleveland Browns superstar deadlifting 655 pounds -- allegedly for a set of three reps!!!!
The former No. 1 overall pick crushed it in the weight room yet again Tuesday ... showing off a trap bar deadlift that even strongman Hafthor Bjornsson would be impressed by.
Check out the clip ... there are so many plates on the bar, they barely fit -- but Myles is able to get it up with ease.
It should be noted .
