1. She Goes Hard…and Allows Herself to Recover

Bruno, known for his snarky sense of humor makes a valid point about his star client in his latest video: She works hard and rests hard. “We all know the importance of rest and recovery, but @kateupton took it to a whole new level and invented the ‘mid-workout nap’. This is genius. She’s been getting personal records left and right in the gym, so I’m definitely gonna try it out myself and with the rest of my clients. As she likes to say: ‘work hard, nap hard’,” he captioned the video. “PS: Those squat jumps in the pool and the barbell-loaded hamstring bodycurls are no joke. Seriously impressive stuff.”

2. She Does Pool Workouts

This isn’t the first time Kate has done a pool workout. “The pool workouts look easy, but they’re actually really tough. Here’s a clip of the hand weight circuit and the bar circuit, but we also do a bunch of lower body stuff, and sometimes we’ll bring the KBox or some dumbbells out by the pool and do a mix of weights and pool stuff,” he wrote alongside another Instagram video of one of her sessions.

3. She Prioritizes Exercise

Bruno told Cosmopolitan that Kate works out five times a week. Her sessions are one to two hours long and consist of strength training exercises like a mix of deadlifts, hip thrusts, lunges, rows, and sled pulls, that work her entire body. "A lot of girls are scared to do strength training because they fear that they're going to bulk up, but if you do the right stuff and focus on the right exercises, it actually helps tighten everything up. Kate has really tightened up her physique noticeably as she's gotten stronger,” he explained.

4. Her Diet Is Clean

According to Bruno “Nutrition is more than half the battle,” when it comes to Kate. “She committed to both the training and the eating right from the get-go, and that's why she's seeing such great results." She eats mostly lean protein and veggies, avoiding added sugars and processed foods. "That's been key," Bruno explained. "If you limit sugar and processed food, that takes care of most of the problems." She also loves smoothies and a glass of wine on occasion. “I don't want it to feel like an unbearable diet. There's not a set cheat day or anything like that, but she does have treats here and there,” he says.

5. She Has Workout Buddies-Slash-Competition

Kate has both a workout buddy and competitor in Chelsea Handler, another one of Bruno’s celebrity clients. The girls are constantly tagging each other in workout videos, trying to one-up each other.

6. Her Lifestyle Is Active

Even when she isn’t in the gym, Kate maintains an active lifestyle. She loves hiking, swimming, tennis, riding horses, and even rock climbing, sharing images of her adventures on social media. She also does aerial yoga.
