Taylor Walker Sinning, a barre instructor and creator of Taylor Walker Fit, recommends using a broom as a "mobility bar."
"Start out with a broom in front of your hips, with your hands gripped just outside of your shoulders," Sinning says. "Lift the shoulders and bring the broom straight up overhead and back as far as you can. Rotate back and forth; increasing your range of motion every time. Focus on keeping your arms straight. If needed, increase the width of your grip."
Up the intensity with squat presses: "Start with the broom behind you, resting on your shoulders, and a forward-facing grip," Sinning says. "With the feet hip-width apart, squat and press the bar all the way up. Make sure to keep your head up, chest lifted, and weight in the heels. Then, extend the legs and bring the bar back to the starting position."
