Why not try it yourself?
Kate Upton has just undergone a total body transformation, but it didn't come without a lot of hard work in the gym.
The model works out with her trainer Ben Bruno five times a week doing a circuit-based strength-training workout that he describes as "not for the faint of heart!"
'We generally start off the workout with a series of strength exercises done in circuit fashion, followed by work with the sled,' Bruno tells PEOPLE. 'Structuring the workout in this fashion provides a cardio effect even though we aren't doing traditional 'gerbil' cardio, like using a bike or treadmill.'
Think you're up to the challenge? Bruno has created a workout exclusively for PEOPLE so that you can train just like Upton.
Warm-up: Brief stretching and foam rolling Lateral band walks
Workout: A1. Landmine squats, 3 sets of 8 A2. Squat jumps, 3 sets of 8
Cool down: Stretching and foam rolling
'This is a just a snippet of her total program,' says Bruno. 'We incorporate a good amount of variety into the routine over the course of the week because she trains five days a week. However, we keep several of the key exercises (deadlifts, hip thrusts, and sleds) in the program consistently and focus on slow and steady improvement, because getting progressively stronger is the name of the game.'
