If you're bored of sit-ups and sick of crunches, you can shake up your core-focused workouts with this personal trainer's 20-minute barre-inspired session — and you don't need any equipment to get started.
Low in impact but high in reps, barre classes combine an element of dance training to help boost flexibility and balance and sculpt strong muscles. They do so by performing a handful of exercises to fatigue, followed by a series of stretches to help lengthen the muscles.
