WORLD RECORD 675 pound weighted plank.
This is kind of a joke but, also kind of serious because I figured out a way to do weighted planks without having to worry about balancing the plates. For anyone counting the weight - I didn't count the weight of the bar and there is an additional 45lb plate on one of the sides to mimic the weight of a traditional barbell. I do believe these bars weight 15-20 lbs but I didn't care to count it.
At the end of each set, it doesn't look like the weight moves much when I drop it because of the bend in the bar from the weight but, believe me, I was really supporting that weight. 🔥
