Thera-Bands are great to use for a plethora of exercises. Use them for arm, shoulder and back strengthening exercises on the road. Slip a theraband into your bag or purse and forget about it until you need it. Thera Bands range in resistance that can be discerned through color. Tan has the least with 1.1 pounds of resistance; the next is yellow at 1.8 pounds of resistance. Red (2.7 pounds), green ( 3.1 pounds), and blue (4.5 pounds) are considered medium resistance products. The heaviest colors with the most resistance are black therabands at 4.9 pounds, silver at 8.6 pounds, and the thera-band with the highest resistance, gold at 11.8 pounds of resistance.
Always inspect your bands or tubing for signs of wear, including small tears, abrasions, or cracks before use. Pay particular attention to the connection point. Always replace the bands or tubing with any sign of wear. With heavy use, such as in a physical therapy clinic, bands and tubing should be replaced every 1-2 months. The bands and tubing will not last forever, and will experience normal wear and tear with extended use. However, they should be safe to use as long as there are no visible signs of wear.
