Between Troian Bellisario (Spencer) doing aerial workouts and Shay Mitchell (Emily) taking spinning classes, the Pretty Little Liars girls know how to stay in tip-top shape. After all, they have to be strong to fight off the "A" team.

Like her PLL co-stars, Ashley Benson (Hanna) also has a unique exercise routine to keep that toned figure. Ash took to Twitter yesterday (April 23), showing off a photo of herself at Trinity Boxing Club in Los Angeles. And even though she's just lounging out in the pic, we must admit, Ashley looks pretty hardcore wearing a hoodie in the ring.

Speaking of hoodies and self-defense, have you seen the new PLL Season 4 promo poster where the Little Liars are rocking red trench coats? Check it out and share your thoughts below!
