Overview
THERABAND's heavy level green resistance band, sold as a 6 yard roll 5 inches wide rather than a pre cut loop. It's the fourth of eight color coded resistance levels, cut to length for physical therapy, rehab or strength work.
Buying the roll instead of a pre cut band costs less per foot and lets you cut custom lengths for different exercises. The color coded system is meant to show progress at a glance as you move up to the next level.
- Level 4 of 8 color coded resistance
- About 4.6 lbs resistance at 100% elongation
- 6 yards by 5 inches per roll
- Natural rubber latex material
Who it's for
Suits people doing structured rehab or PT style band work who want the same latex material clinics use and don't mind cutting their own lengths. Not for someone who wants a ready made loop or handles straight out of the box.
What buyers say
From Amazon customer reviews.
Buyers repeatedly note this is the genuine THERABAND product, not a knockoff, and several use it to continue PT exercises like shoulder rehab at home. One reviewer with experience across multiple band brands felt the heavy label ran closer to medium strength, while another found it stretched more than a previous band they had bought elsewhere.
Strengths and trade-offs
Drawn from this product's published specifications.
- Genuine latex construction used in clinical PT settings
- 6 yard roll lets you cut custom lengths
- Color coded system tracks progression to the next level
- No handles or anchors included
- Some reviewers found heavy resistance milder than expected
- Requires cutting to size before use
Performance notes
At 100% elongation the green heavy band delivers about 4.6 lbs of resistance, rising to 6.7 lbs at 200% stretch, a step up from the lighter colors in the eight level system. Because it's natural rubber latex sold on a roll, resistance runs continuously along the strip, so a shorter cut feels stiffer than a longer one of the same band.
