Input:
This band is perfect for those of you who do some recreational resistance or weight training and also travel regularly. If you do a significant amount of muscle training at high weight or resistance, this will not offer much challenge to you. You should be aware before buying this, it is NOT a replacement for going to the gym. I wish it offered more resistance, but it doesn't. You're not going to open the package and find a magical rubber band that somehow gives you 200 pounds of resistance without you tearing your door off it's hinges. No, I'm afraid that fantasy product doesn't exist. This is a fine item for keeping you active if you get bored while watching TV. If you need something to use in a hotel room this is ideal for it's small luggage footprint as well as it's ease of use.

There are a large assortment of exercises that can be done with this band with or without using a door. You can curl it by standing on it and pulling upward, shrug it, do lunges with it, do rows with it (door needed for that one) and simulate pull ups (also needing a door for this one) to a reasonable degree. You can also adjust your own resistance on some exercises that require you to stand on the band by widening your stance. It's a very logical and simple product to use.

I don't recommend the purple band to those new to resistance training. There are other colors representing other weight simulations that you should probably consider, although the pricing is so cheap you can probably get a couple and work your way through them if you really wanted to do that.

A WARNING: Read the directions before you use this. For example, you may be tempted to close the strap for door use into the top part of the door, this is incorrect and could damage your door. You close the strap into the door near a hinge (definitely not near the knob). While this band does not offer much resistance, I strongly suggest wearing shoes when using your feet to provide tension as having it snap back into your face would probably not be a pleasant experience.

To revisit: It's not a gym replacement so don't pretend it is and then be disappointed when you buy it, that's just illogical. It's highly portable. It's highly diverse. It offers decent resistance for recreational or travel use when unable to use a gym or home exercise equipment. It could snap back dangerously if used in ways contrary to those spelled out plainly in the instructions.
