The 24-year-old wore a black tank top and zaffre workout capris, her outfit tight enough to show off the supermodel figure all her workouts have won her.

Her platinum blonde hair in a bun, the she refused to betray a trace of discomfort on the onetime face of Guess, completing all five deadlifts with perfect composure.

The video was originally posted by her trainer, Ben Bruno. When the Michigan native reposted the video to her own Instagram, she included Bruno's original caption.

'Kate Upton (@kateupton) crushes "1.5 rep" trap bar deadlifts with great technique,' he'd written. 'Strong! She makes it look easy, but trust me, these are brutal. Great for the legs and butt ����.'

No slouch in this field, Bruno has assembled a client list crammed with celebrities, and frequently posts videos to social media of them exercising.

On Saturday, he uploaded footage of Chelsea Handler completing a set of split squats, her hands gripping a medicine ball. In a tribute to her resolve, his caption revealed the clip was filmed at 6:45am.

Phil Rosenthal, best known for having created the smash sitcom Everybody Loves Raymond, commented, 'Funny. When you wake me at 6:45am and ask what I'd like to do, I always say this.'

Other name-brand trainees include two-time NBA All-Star Roy Hibbert, tennis legend Caroline Wozniacki and New York Rangers winger Chris Kreider, as well as models Barbara Fialho and Nadine Leopold.

Before Thursday, the last of Upton's many appearances on his page was only three weeks ago. The cover girl crossed the room pushing a sled that, with the combination of a stack of weights and Bruno himself perched atop it, came up to 540lbs.

Luckily for her, she had a beer helmet on. Her West Hollywood-based trainer's caption read, in part, 'This is her personal best (VERY strong!), so I think we may have discovered a new secret for performance enhancement.'
