Nationals

Nationals slugger Bryce Harper is a big, strong dude. He's also a polarizing figure who could be worth upwards of $400 million to either the Nationals or the Yankess, or pretty much any MLB team.

So when he posts Instagram videos of himself lifting weights, folks like to comment ... a lot. 

Here's Harper deadlifting 505 pounds, admittedly without the best form. He also shared a video of his squatting routine. 

A sampling of the fan comments:

"squid_castillo: So how long until you have to sit out with a back injury"

"drewjohnston22: @dboss923 pumbeling his back. Dodgers, all aboard the 'ship ship"

"miredsoxpride: No this isn't how you make an MVP... This is how you get an elite talent hurt. B. Harper has tremendous potential because of his unique skill set not because he can deadlift 505 pounds. 1st rule of strength and conditioning coach, "do no harm!""

"jdeese11475: Obviously no National's trainer around. Bryce longevity, not ego bro! Go for form! Would hate to see another promising career fade into obscurity."

"maisor: Keep that back straight and neutral. You need to earn another MVP not a bulged disc for a Instagram video."

"3rdbaserocks: @bharper3407 , dude,. Please save your knees so I can come watch you when the Nats visit Seattle. Heavy squatting is not necessary. Your knees will thank you for it later."

"mrkcrss: Herniated disk will cost you $200 million"

So, are fans right to be freaked out by Harper's weighlifting? And which one of you wants to step up and say you could do it better?
