SPRI ES503R Xertube Resistance Band with Door Attachment and Exercise Charts (Purple, Very Heavy)

I couldn't believe how fast my bands got to me - a day earlier than the earliest approximated date!

I've been using a red SPRI Xertube band with P90X for about a week. I do NOT recommend this resistance band.

Here are some problems with it:
* it claims to offer resistance for the "fit" to "very fit" range. I can do 20lb bicep curls, 10 rep max. This band lets me do curls forever. If I make a loop, things improve but:
* if you use loops or shorter sections of the band, it's hard to keep track of how much you "lifted". With dumbbells, it's clear and you can track your progress.
* the handles are not cushioned or rubberized. They're simple plastic and tend to rub against my palm.
* the handles are not extensible with additional tubes. Compare that to Lifelineusa bands, where you can put up to three bands on the handle and greatly vary the resistance.
* as another reviewer mentioned, bands don't really work for muscle gain. They work for strength and toning.

Pros:
* much cheaper than dumbbels, and easy to carry around.

I recently bought the SPRI Resistance Band. I have to admit, at first I was rather skeptical about the use of over-sized rubberbands, but now I'm a fervent believer. They're portable, light weight and can provide quite a workout. They come in a variety of resistances for just about every one. Start your engines and get ready to burn! Thank you. Rich

Performs exactly as advertised. I have all of the different sizes and they all work well. The strap that comes with the band for the door works excellent.

This exercise band has really good resistance. It's strong enough to use for a chest workout which most other bands aren't. Recommended.
