User Review: I bought this resistance tube because I wanted a workout tool that would supplement my free weight and heavy bag workouts without causing more stress on my joints. This tube has worked perfectly for that purpose and I am able to accomplish multiple types of exercises with this.

I mainly bought this tube because I cancelled my gym membership as, contrary to the reason I was going, I was getting too lazy to to get to my $10/month gym on days I had preset for myself to go. I decided to instead do workouts I could do strictly at my own house. I already have a pair of dumbbells and a muay thai bag so I started using those exclusively and they're great tools to accomplish my fitness goal of being able to eat more cookies on the weekend without feeling too guilty. However, I was missing out on exercises I used to enjoy at the gym because the machines I used to use were not available to me at my house. In particular, I was missing out on the pulley machines which would give my muscles/joints a rest from having to move those "heavy" weights I was using. Enter the resistance band, a great tool to give those tired muscles/joints a rest while still providing a substantial workout for those days when I feel the need to exercise but don't feel the motivation to use the dumbbells or wander to my garage to hit my bag.

I purchased the blue (heavy) band and it has provided me with the perfect amount of resistance for the workouts I use them for. I have short arms so many times I will wrap the band around my wrist and grip it lower, which is double-great because it also makes the exercise that much harder, yay! It's hard to really describe how much actual resistance you're getting and which band is good for you as, well, there's no physical number attached to how much weight it is. However, you should also know that most exercises can be tailored to your fitness level, simply by changing where you grip. Case in point, my wife has also used this same blue band for some exercises I showed her by changing where she grips and altering her stance as well.

I am a big believer in resistance band training and love the flexibility it gives you when it comes to the types of exercises you can. Your imagination is truly your only obstacle and if your imagination is not quite as active then there are also tons of helpful sites you can visit to find the perfect workouts for what you are trying to accomplish.

I have had no problems with this band and it feels sturdy enough to last for a while. Time will tell and if it decides to snap or fail on me then my review will be updated to document its shortcomings.
