I've worked out at home for years, but only recently have I begun incorporating exercise bands into my strength training. I've had a few flat-type bands that have wound up getting worn and snapped over time, so I wanted to invest in a higher-quality band. Happily, this SPRI tubing perfectly fit the bill WITHOUT breaking the band! This is a very sturdy, very versatile little piece of exercise equipment. You can use it to replace weights in your usual workouts, which allows you to work your muscles in some new and unique ways (refer to the included exercise chart for ideas). When at home, you can actually use the tubing WITH your weights to add greater resistance throughout the entire muscle movement, OR you can pack your tubing with you when traveling--so light and convenient! Finally, the included door attachment is easy to use and allows you to perform an even greater variety of exercises. I wasn't sure which strength tubing to purchase, but I am an intermediate to advanced exerciser, and the medium (red) is perfect for me, as it is easy to adjust for either more or less resistance when needed. Highly recommended! 5 stars

This product is amazing. I recently did 5 weeks of bootcamp and we used these resistance tubes every time for biceps, chest, back and shoulders. Its amazing how effective these are and all the time you are just using your body weight. You can make it as easy or as difficult as you want. I had to get them. The green one was a little too light for me and the blue one is a little too tight for a beginner woman. Best part is you can take this lightweight exercise gear anywhere you want and have a good muscle toning workout. Think you can google up the different exercises you can do with these. Plus for the price, it is so cheap, you dont even need to think twice. 5 stars

Simple way to do resistance exercise training. The door attachment easily jams in a closed door to allow the tubes to be used for top-down exercises. Despite all the hype over the fancy exerciser systems, the Xertube Resistance Bands are a great way to exercise. Easy to pack, they allow you to keep up an exercise routine while traveling. 5 stars

I bought this product around a month ago. I thought it wouldn't be a bad idea since I'm unable to go to the gym more than 4 times a week, and that I would probably use this for some heavy resistance, but the very heavy turned out to be much lighter than I thought, and I doubt the Ultra heavy is much of an increase. To be honest I don't really benchpress that much compared to others, around 90 pound dumbells, and I could easily do around 18 reps on the Xertube. Don't get me wrong it's not a bad product except their resistance isn't so resistant. Women and a casual lifters might enjoy this product, and this product can give a great deal of toning, but if you're a heavy lifter, don't count on it for anything other than some light toning. It just doesn't have enough resistance. 3 stars

This item is well made. The tube is beefy and the handles are sturdy. The included exercise booklets are lame. They have dated black and white photos showing disinterested people doing lack luster exercises. 4 stars
