Bought these to use in lieu of the rubbery ones at the Y - which took longer to get on and off and adjust the rolling than to do the actual exercises, especially if you do circuits. These are sturdy and nicely finished, overall excellent quality. They eliminate the rolling and pinching of the rubber bands. Being fabric, they don't "feel" as elasticky as the rubber bands, but the resistance is still there. Comparing the fabric "strong" to the "strong" black rubber bands when doing clamshells, it is harder to open the fabric band than the rubber band. The "light" band is useful when stretching in lieu of a towel for stretches I can't quite reach without help, and I've been able to incorporate all three bands into various floor/standing exercises (leg lifts, squats, even arm stretches). If you feel the workout is too easy, hold the stretch for a few seconds to increase the resistance; you'd be surprised how that can add difficulty to an otherwise simple exercise. It not necessary to have access to a fancy weight machine to get a workout! Looking forward to working these into my exercise routine, especially on a day when I can't make it to the gym. Love that they are transportable enough to take on a trip, or even into the office.The storage pouch is nice, and also well made. Have not looked at the videos yet. Really appreciated the included card from the company founder to "Dear Sister" and thanking the buyer for their purchase. Although anyone is welcome to buy these, of course, in pastel colors or the more neutral set, it's a nice feeling of female fellowship to be addressed this way.
