Rated 3.6 out of 5 by 16 reviewers.
Rated 3 out of 5 by I'm too tall for the bands The resistance bands came in my starter T25 kit and I feel like i'm going to tear a back muscle trying to lift them over my head. Apparently they're not built for 6'2" tall women with wimpy girly arms. November 11, 2014
Rated 3 out of 5 by great bands but poor handles One of my handles broke the first day but I only use one of the bands so I have an extra set of handles to use. May 10, 2014
Rated 2 out of 5 by Difficult to use effectively The bands are a good quality. The bands slid into the hands but when you work out you can push the band out by accident. If you want to switch between the bands you need to pause and switch. The thicker bands are difficult to get in while the thinner one slides out. August 22, 2013
Rated 5 out of 5 by Strong Bands, Handles WORK The bands are very durable and perform their jobs well, but the major reason why I'm writing this review is to inform people that the handles WORK but there is a correct and incorrect way to use them. Put the band in the wrong way? Oh, I'll just pull the handle around so it works anyway right? Wrong. When putting the band in the handle, make sure the side that says "US PATENT" is facing towards your knuckles. If reversed, the band will slip out when tension is added, and potentially wipe out completely. This will probably cause you to get frustrated and write a bad review. September 25, 2012
Rated 5 out of 5 by High Quality and durable bands I don't understand the negative comments regarding these bands. I have used them a little for pullups for P90X when my rotator cuff was bothering me. I also used them in two rounds of P90X2 without any issues what so ever. Just order extra handles so you don't have to swap them out. I first ordered bands online and they were real junk. Don't waste your time and money on others, these are quality bands.

Rated 2 out of 5 by Good bands, bad handles The fact that they sell extra handles separately should tell you something. You're going to need them! March 14, 2012
Rated 1 out of 5 by Too flimsy I attempted to use these bands with p90x for the biceps workouts, and while they provided good resistance, they would snap if i pulled them too hard, thus whipping me in my own leg. It was hard to do curls worrying whether or not you are about to get whipped by your own resistance band! I spend the money on a dumbbell set, it was well worth the money. December 10, 2011
Rated 2 out of 5 by Resistance bands The band itself is good quality but the handles are of poor design. The handles slide during use making some exercises difficult and fraying the nylon portion of the handles. I have only used these bands for a week and a half and already the nylon is fraying. These are not the same handles as represented in the P90x DVD;'s. August 23, 2011
Rated 3 out of 5 by Good quality but set lacks resistance range. The product is everything it says it is and I have no complaints about the quality. However, For someone who doesn't have weights I found that it doesn't have the lighter resistances needed for certain exercises in the P90X program. Even in the videos the band demonstrator is using a red colored band for a lighter resistance on certain exercises. They should swap out one of the blue or black bands for the lighter red one so that it comes with everything you need for P90X. August 5, 2011
Rated 4 out of 5 by great bands, handles could be better These bands are still far and away the best in the industry (which can be said for almost all their products)... but the handles only last about 180 days for me. I stocked up to compensate. I'm not certain how you could improve the handles, but I'd love to see them improved. June 1, 2011

B-LINES® Care and Safety Instructions

For your safety, please read before using B-LINES:

The B-LINES Resistance Bands exercises are athletic activities involving pushing, pulling, and sometimes jumping. If you have had physical problems or surgery, particularly of the bones, joints, or muscles (and especially any history of problems with the knees, lower back, or neck), or have been inactive or sedentary for some time, you should consult a physician before starting to use the bands.

Also, because the bands have elastic properties, you should take special precautions to avoid being injured by the bands breaking or snapping back. Inspect the equipment before and after every use for scratches, nicks, cracks, and abrasion spots. Test each band's resistance carefully in each new position and begin all exercises slowly, as directed.

The greatest degree of care has been taken by the manufacturer of the B-LINES Resistance Bands to ensure that they are as safe as possible. It is the responsibility of the user to read and comply with the following safety precautions. Failure to comply may result in the possibility of injury. See your doctor before beginning any exercise program.

  1. DO — Any and all exercises rhythmically. Don't jerk or lunge, but keep your movements smooth.
  2. DO — Always resist the band back to the starting position. By resisting the band back (eccentric contraction) you are achieving a training effect both ways—so important in developing and shaping the body.
  3. DO — Avoid excessive heat around the band, sharp objects on the floor, or shoes that are not smooth, and examine before each workout.
  4. NEVER PLACE HANDLES (STIRRUPS) ON YOUR FEET. Only use your hands; doing otherwise can cause injury.
  5. DO — Increasing the number of repetitions is more beneficial than increasing the resistance. Example: If you can do 10 repetitions easily, increase to 16 or 20 repetitions rather than increasing the resistance.
  6. DO — Always keep a good wide stance or base when doing exercises such as chest flys, standing presses, or sporting simulations. Never lean. Go slowly, especially in the beginning.
  7. DO — When doing repetitions, breathe normally. Don't hold your breath.
  8. DO — For added comfort and improving grip and avoiding any possibility of the band slipping, wear workout gloves, especially when doing presses. Grasping stirrups firmly also helps develop the hands, wrists, and forearms.
  9. DO — Wear exercise shoes only. Never work out barefoot.
  10. NEVER tie tube in knots as this may cause band to break.
  11. NEVER store your cables in direct sunlight.
  12. NEVER stretch the cable more than two and a half times its length.
  13. This product is not designed or guaranteed for permanent outdoor installation.
  14. DO — Because B-LINES Resistance Bands have elastic properties, you should take special precautions to avoid being injured by the bands breaking or snapping back. Examine each band before and after each workout session. Look for nicks and worn spots on the band. If any defects are discovered upon inspection, return it to Beachbody. If the defect is a factory defect, it will be replaced at no charge. If it developed from misuse by the user, there will be a minimal charge.
  15. DO — Check all sewn components to ensure that there is no loose stitching or unraveling. If any defects are found, do not use the product and return it to Beachbody for replacement.
  16. DO — Clean the bands with soap and water only; never use chemicals of any kind.
  17. DO — Begin slowly; remember that your muscles may not be in shape and that it doesn't take excessive overloading to cause them to respond. In fact, if you dive into an extremely rigorous program, your body will not have enough time to adjust or adapt to the stresses you are imposing upon it, and more harm than good will result. Again, the B-LINES exercises are well adapted to this purpose, and are easily adjustable. As your muscles begin to respond, we encourage you to increase both the number of reps and your speed, rather than increasing the resistance.
  18. DO — Use only as directed.
  19. DO — We strongly suggest and recommend that you replace the B-LINES Resistance Bands unit (cable/stirrups/Door Attachment) at least once a year. If you use the B-LINES Resistance Bands more than three times a week, replacement is recommended every six months. Contact Customer Service at 1-800-565-4807 to order your replacement bands.
  20. Two people should NEVER use a B-LINES Resistance Band at the same time! Use by two or more persons simultaneously may result in injury.
  21. Children under the age of 16 should only use the B-LINES Resistance Bands with adult or professional supervision. Supervision should ensure that the child uses the equipment as explained. We question the need and ability of a child under the age of 12 to handle the B-LINES Resistance Bands properly. Exceptions can be made for individuals in that age range who are involved in athletic training, but even then, professional supervision is recommended.


The B-LINES Resistance Band is well-designed and a serious exercise machine. IT IS NOT A PLAYTHING. If treated with care and seriousness and used completely in accordance with the directions, it will give you fine service. Abuse can quickly ruin its usefulness. Beachbody is not responsible for any immediate or consequential damages resulting from any abuse whatsoever or from any failure to follow these directions.
