Try These Mat Pilates Moves If You Miss Your Studio’s Reformer

This move challenges the smaller stabilizing muscles of your body to work in unison with the core and postural muscles, Speir says.

• Start on your hands and knees.
• Extend one arm out by your ear and the opposite leg straight out behind you.
• Lower down that same arm and leg down to the starting position.
• Repeat on the other side.
• Continue for 10 sets.
