On Mondays, the day most ballet dancers spend soaking their aching feet, Skylar Brandt, a soloist at American Ballet Theater, takes a different route. First, she has ballet class, then Pilates; next, a two-hour private coaching session at a City Center studio and, finally, a visit to the chiropractor.

“Sometimes my days off are harder than my days at A.B.T. just because I make it that way,” she said. “It’s a total investment in myself.”

She likes to work. Soloists, generally, have down time — too much for Ms. Brandt’s taste. “I just turned 27, and I feel like at this point I should be starting to experience more growth,” she said. Or some growth. It’s not just about being promoted; she really just wants to dance.

At Ballet Theater, Ms. Brandt has found that her best opportunities have arisen from filling in for injured dancers in prominent parts like Medora in “Le Corsaire,” Princess Praline in “Whipped Cream” and Columbine in “Harlequinade.”
