Kalina Stoyanova found Toolbox Pilates when she came to DC in 2015, and it quickly became the only workout she actually found herself looking forward to. She was immediately hooked after improving her upper body strength, posture, and overall muscle tone and decided to start teaching in 2016.

Kalina likes her classes to be challenging and creative yet accessible, to give others the same confidence in the exercise that she discovered through her practice. Focusing on breathing and engaging throughout class (usually to a soundtrack of early 2000s bops), Kalina’s full-body workouts always end with a lengthening stretch and signature final deep breath.
