While losing weight after a pregnancy is a struggle for any new mom, the pressure to return to one’s pre-baby weight is no doubt amplified in Hollywood.

No one knows this better than actress Blake Lively, who has given birth to two children in the past three years and starred in four (going on seven) films in the same period of time.

After her first pregnancy with daughter James, Lively miraculously regained her six-pack in a few short months ahead of production on The Shallows (2016). Though it seems like movie magic, in reality, Blake worked incredibly hard to get back in shape.

The 30-year-old and her trainer Don Saladino (whom she shares with husband Ryan Reynolds), focuses on strength training as opposed to cardio. Pre-production on The Shallows, Lively increased her training sessions from one to two times a week to five or six. “We would do an upper body workout Monday, lower body Tuesday. Wednesday was a playful pool workout where she would do laps,” Saladino explained. “Thursday was upper body, Friday lower body, and Saturday we were focusing on the accessory movers: the arms, the shoulders.”

After Lively gave birth to her and Reynolds’s second child in fall 2016, however, the Gossip Girl alum took a more leisurely (though no doubt hardcore) approach to dropping her baby weight.

On Monday, Blake shared a photo of her and her trainer and thanked Saladino for pushing her. She also commended herself for her impressive efforts.

“Turns out you can’t lose the 61 lbs you gained during pregnancy by just scrolling through instagram and wondering why you don’t look like all the bikini models,” the mother of two joked. “Thanks @donsaladino for kickin my A double S into shape. 10 months to gain, 14 months to lose. Feeling very proud :muscle::grin::muscle:.”

[MUSIC] Hi I’m Kim with InStyle. I’m here with owner of Drive 495, Don Saladino.Hello. Hello. Thanks for having me. Thank you for joining us. Awesome, excited to be here. He trained Blake Lively. You have for what eight years God, probably seven years already. Seven years. And he’s going to show us how to get a body like Blake. Ok, so one important thing is that we want to do exercises that we kill two birds with one stone, okay? So one of them right now that I love for you and for her is something called a windmill. So, let’s grab the dumbbell. Okay. Use the dumbbell, kettle bell or weights are too much, you can go with no weights. What I’d like to see you do is Angle your feet in the direction I am. Okay. Put that weight directly overhead and what you’re gonna do right now is keep that weight up and give me a little booty hip bump. So bump towards me, yes, yes, yes up. So what I love about this right now, as you can see, let’s bend that front leg a little bit and keep the back leg, yes, exactly. So what we’re doing right now is we’re really stretching out, working that glute hamstring, but we’re also working the core a lot. This is hard. It’s sad. It’s, you’re gonna feel it. So it’s one of those things where we are getting a lot of lat work. We’re getting a lot of work to the shoulder, the arms, but we’re also getting this rotational component where we are hitting the core. And we’re hitting the hamstrings, it’s really a total body mover and I absolutely love it. So it’s on of those things. So just give me like ten reps. I think we are about there right now. Right now. So be it this way? Yes, so we’re pretty much go. Hold on a second, we’re going to angle up and we’re going to [UNKNOWN] this way. Exactly. So, giving a little booty shout right now. And let’s go one more and we’re going to stop At the top for one second, and rest. Okay, so one thing I want you to think about with this is we’re gonna start with two sets of ten repetitions. Really, really simple. I want you doing them twice a week. Two sets of ten twice a week. Right. Okay. And the intensity doesn’t have to be crazy. Everyone’s under this mindset that you gotta come in, it’s just no pain, no gain, I’m gonna go with the throttle to the floor, that’s not what it’s about. It’s about focusing on really good technique. Having, it’s very important, you gotta have fun with these exercises and it should be short and sweet, so. It’s really that simple. And that’s one of the reasons you love this move for Black, right, cuz it has to be fun? It’s gotta be fun but it’s also has to be purposeful. Like, what are we trying to do? We want her to be strong, we want her to be tight, we want her to feel good, so, this is one of these exercises right now that we’re really. Tapping in a lot of different areas on the body. We’re not just standing there doing our curls which is still fine but we’re really with the time we have, we’re really kind of attacking, getting in and getting out. Mark, it’s true that we don’t have a whole lot of time, right? Nah It’s a crazy schedule, she’s now a new mom and so I’m really happy for her. She’s fantastic. Good! And for weight, you recommend ten pound, eight pound? Yeah, what I would do is even start with no weight at first. So we’re going to start with the arm up. We’re going to do that hip bump in here. Notice how my arm is directly over my head, standing back up vertical. So you could start with no weight and really just start getting that connection of feeling the stretch in your hip glute area. And then after that we can go grab a weight. Okay. Go vertical with the weight, dumbbell, cattle bell. Don’t feel like you have to go so heavy in the beginning, your body will know, and it’ll give you that response of, all right it’s time to go a little heavier, it’s time to challenge myself a little bit more. I like it. It’s easy. Thank you so much. Shouldn’t be tough, thanks.
