Length, grace, and a healthy body. These are the focuses of barre3 founder Sadie Lincoln. To achieve these results collectively, however, Sadie knew she needed to come up with a completely new routine. Working with yogis, professional dancers, doctors, and athletes, she created the barre3 system. This three-step sequence consists of isometric holds, low-impact movements, and recovery stretching. The combination strengthens cores and aligns postures while sculpting long, lean muscles and burning calories.

While upbeat music fills the studio, instructors lead small groups through a heart-racing sequence of yoga-inspired poses and Pilates-based exercises. The ballet barre comes into use when striking muscle-building dance poses and stretches.

It's a system that has had proven results, which has spurred the successful growth of barre3 locations throughout the country. An easy-to-follow routine, barre3 can also be performed at home with online workouts. These workouts are designed to fit busy schedules with routines that range from 10–60 minutes. All that's needed for an online workout is a barre3 core ball, weights, an exercise mat, and a sturdy, waist-high surface, such as the top of Danny DeVito's head.
