Brie Larson in Bathing Suit Says "Summer is Here"

Brie Larson is a superhero on screen (as Captain Marvel, and soon to be another; in the Fast and Furious sequels, everyone seems superpowered), so it’s no surprise to see her bruised from the gym. “Summer is here but bruises from training are in every season 😂,” she captioned a new swimsuit photo. How does she stay so fit? Read on to see 5 ways Brie Larson stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She Does Planks

Larson works out with Jason Walsh of Rise Movement, who put her through a number of exercises in one video, including a classic plank. When doing a lateral plank, don’t put your hip too far back, Walsh advises Brie, and put your top foot a bit in front. To start: “Lie on your right side on an exercise mat with extended legs, placing your left leg directly over your right leg and and stacking your feet one on top of the other. Place your right elbow directly under your shoulder, align your head with your spine and keep your hips and right knee in contact with the exercise mat,” says ACE Fitness.

2. She Does Hip Thrusts

A barbell hip thrust “is basically a glute or hip bridge exercise with external resistance. The exercise involves lying face-up on the floor, or with the shoulders resting on a bench, with the knees bent and feet flat on the floor. The exerciser places a barbell across the top of the hips (usually on a pad) and presses the hips upward for a number of repetitions. This exercise focuses specifically on the hip extensor muscles of the gluteal complex, namely the gluteus minimus, gluteus medius and gluteus maximus,” says ACE Fitness.

3. She Does Pull Ups

Brie does neutral grip pull ups and holds the position when up, with her knees pulled up. “The shaking will ensue within probably five or 10 seconds. You just kinda Zen out,’ said Walsh to her. “By pulling the knees up, it actually keeps that spine neutral as engaged.” Brie held it for a full minute!

4. She Uses Bands

Walsh had Brie use a band for a Band External Rotation, which targets your infraspinatus muscle, part of the rotator cuff. This will get her some super-strong shoulders. “Resistance tubing is a lightweight, portable, inexpensive strength training tool. The tubing provides resistance when stretched,” says the Mayo Clinic. “You can choose from many types of resistance tubes in nearly any sporting goods store. In general, the lighter the color of the tubing, the lighter the resistance. Likewise, the darker the tubing, or the shorter you make the tubing, the greater the resistance. You can use resistance tubing to strengthen virtually any muscle group, both in the arms and the legs. As you get stronger, you can use tubes that provide more resistance.”

5. She Eats “Bridge Meals”

Brie eats bridge meals—a between-meal snack. "The purpose of a bridge meal is to get to lunch so that you don't overeat lunch," her nutritionist Dr. Philip Goglia told People. "You're using fat metabolism and that will be your bridge meal to get to dinner so that dinner is an appetite environment that will not allow you to crave carbs because you've already eaten… you're kind of full. You're not in low blood sugar." Vegetables or nuts are great go-tos for a bridge meal.
