"Take breaks between activities," suggests Brick, who gardens carefully to avoid exacerbating an old back injury from her high-school field hockey days. "Roll your shoulders back, reset great posture, shake out your arms and legs and take deep breaths. Then you can get back to work. Even if you're in great shape, you're not necessarily in gardening shape. It requires twisting, turning and lifting — gardening uses different muscles than a barre class."
