Stand with feet hip-width apart. Leading with your butt, sit back until your knees make a 90-
degree angle to the floor. Hold your arms in front of you for counterbalance. Don’t let your knees come forward beyond your toes. Keep your lower back long and your center body tight. Repeat squats for 30 seconds.
To make it harder: Hold dumbbells at your side. For even more challenge hold your arms over your head. (Mark Mulligan / The Herald)
