She’s an Instagram fitness star with more than 18 million followers thanks to her killer body and 'perfect butt'.

Sommer Ray, 21, is the daughter of a bodybuilder dad and a mom who constantly worked out, too. She says that she began lifting weights in her home gym at age 14.

Ray, who was considering getting a fitness certification, saw Instagram modeling as a potential source of revenue. That strategy has since paid off, from ad campaigns for big brands to Ray's own projects, like her recently launched fitness app, Evolve, which offers equipment-free workouts and meal plans.

Ok, so how do we get THAT butt:

Sommer hits the gym about 5 times a week for up to a 90 minutes on alternate days to give her body time to recover. 2 of those 5 days, she works her lower body. "If my glutes are sore, I tell myself, 'I probably shouldn't work them today,' " she says. "I just listen to my body."

Gym booty-building plan:

• Warm up

• 6-minute stair stepper warms up: alternate between 1-minute normal climbing and 1-minute skipping steps.

• Booty builders

Do 15 reps of each move at a low weight. Perform 3 more sets of 15, increasing weight after each set.

- Leg press machine

- Cable kickback

- Abductor machine

- Adductor machine

- Hip thrust on hamstring curl machine

- Single leg press on assisted pull-up machine

- Donkey kick with ankle weight

- Squat on a smith machine

• Cardio

• Jump rope: jump for 1 minute. Cool down for 30 secs. Repeat for up to 6 minutes.

No honey, that is not fake. Sommer Ray is the epitome of hard work and confidence. She made it clear that she didn’t achieve her body without weight workouts. That sculpted is a product of weightlifting.
