TheraBand Professional Latex Resistance Bands, Individual 6 Ft Elastic Band as Exercise Equipment, Physical Therapy, Pilates, At-Home Workouts, 6 Foot, Multiple Colors and Resistance Levels Available

The black is the strongest.

I have used Theraband for many years - and I like the Black level, which has more heft than some of the others. You can wrap it around your wrists to shorten the length, which increases the effort to work with it and also increase the workout. These are very packable because they pack flat, so they are terrific for travel, and take up no space in a suitcase or carry-on bag. Over a long period of time, mine have sometimes snapped from so much use - but the shorter lengths can still be used, and I do. Definitely recommend Theraband to people who like to work out regularly.

Good product

Theraband quality, good stretch

Works just as expected, no rips or suprises or anything. I upgraded from the blue one, I really like how Theraband brand has colors so you know which one you should go to next if you are doing your own at home therapy.
