The Vampire Diaries star Nina Dobrev does intense workouts with personal trainer Harley Pasternak. Pasternak took to his Instagram recently to reveal a very exhausted Dobrev.

Growing up, Dobrev was a competitive gymnast, so she knows what it’s like to train hard and push her body. She has said she enjoys working out, as it not only boosts her happiness, but makes her feel accomplished too.

Some fitness secrets shared by Dobrev are that she enjoys swimming, yoga, and spinning, as well as working with a personal trainer. Her previous trainer Steve Moyer explained to Shape magazine that when Dobrev trains she’s “devoted, focused, self-motivated. It sounds so cliché, but she truly is a pleasure to work with because she has such a warm personality and works so hard when we’re together. Devoted, focused, self-motivated.

What keeps Dobrev lean and slender is her love for hot yoga. She has been known to practice yoga three to four times a week, with Bikram yoga being her favorite.
