One of the most widely recognized pieces of PT equipment is the Theraband. Meant to provide resistance without the need for bulky and sometimes dangerous weights, Therabands are a practical way to (re)gain strength and to stretch various muscle groups.
One aspect of Therabands that many people fail to realize is that they are color-coded to signify the amount of resistance each particular band provides:
Yellow Resistance Band - 1-6 pounds of resistance (lightest) Red Resistance Band - 2-7 pounds of resistance (light) Green Resistance Band - 2-10 Pounds of resistance (light-medium) Blue Resistance Band - 3-14 Pounds of resistance (medium) Black Resistance Band - 4-18 Pounds of resistance (heavy) Silver/Gold-10-40 Pounds of resistance (heaviest)
Now next time you visit PT you'll know exactly what those bands are for and what each color means!
