Eve Guzman was featured in PEOPLE’s 2015 Half Their Size Issue after going from 277 lbs. to 138 lbs. by dramatically decreasing her portion sizes and sticking to a high protein, low-fat, moderate carb diet. Since her weight loss, the genetic toxicology research assistant and mom of two, 33, has coached people all over the country on how to lose weight, helping them drop a combined 2,950 lbs. In the next phase of her journey, Guzman is preparing to compete in a figure competition, and will be sharing her preparation in an exclusive PEOPLE blog. You can also follow her on Instagram.
Khloé Kardashian is demonstrating exactly how she works out her most famous asset.
The secret to a defined derriere? According to Kardashian, 31, it’s squats.
In her latest Khlo-Fit video, “The One Exercise You Need to Boost Your Booty,” the reality star holds a squatting position on a Bosu ball. The ball creates instability and makes the move more challenging.
“Your core is going to fire and your legs are going to recruit different muscle firing patterns to stabilize your position, which makes the muscles more efficient,” Kardashian’s trainer Gunnar Peterson explains.
If you don’t have a Bosu ball, Peterson says you can use stacked towels, a pillow or an air mattress to stand on while squatting.
“I can do it on anything that’s going to give me instability, and it will challenge me that way,” he says.
Peterson also demonstrates how to do the Kocktails with Khloé host’s slide-board ab workout at home. Cookie sheets on a carpet achieve the same gliding effect, so to do Kardashian’s move, place your hands on the sheets while down on all fours, and slide your upper body in and out.
“The key is on the way back, not to drop the hips and butt back so you disengage,” says Peterson.
Kardashian says her workouts help keep her on track – both mentally and physically.
“I definitely think the physical and the mental go hand in hand,” the newly single star told PEOPLE last month. “I feel so good in the gym that it [affects] the rest of my day. It’s a healthy addiction. It’s like buying your sanity!”

I gained 60+ lbs. during my pregnancy, and I thought I’d bounce right back after my daughter was born. Needless to say, that didn’t happen.
I loved being a new mom and cherished every moment with my baby, but I couldn’t help feeling down on myself every time I passed a mirror, only to be met with the disheveled reflection staring back at me.
I had given up on taking care of myself, not just from an aesthetic point of view, but emotionally too. I realized if I wanted to be a happy, healthy mom, I needed to be good to myself and nurture my mind and body.
To get myself back on track, I signed up for every exercise class you can think of, only to find myself dreading each one. This went on for a few years until I met my coach, Tyler Gaskin, who introduced me to CrossFit. It became a huge turning point for me … for the first time in my life, I looked forward to working out. I was hooked.
