​Workout Bench

Bowflex is known for their all-in-one, space saver fitness machines. However, the company appreciated how useful a freestanding bench is to dozens of exercises. The 5.1S incorporates the space-saving concept of Bowflex multi-gym machines into an adjustable bench.

They understood the bench needed to be lightweight, but sturdy as well. Bowflex was also determined to maintain their demanding company reputation for quality. Here's our review of the Bowflex 5.1S Adjustable Bench.

Why a Freestanding Bench?

Bowflex machines are some of the sturdiest, most versatile exercise machines on the market. However, if you wanted to perform exercises an isolated bench, you could not use the one built into the machine because it was attached.

Rather than compromise the critical strength and sturdiness of the Bowflex machines, the company chose to build a separate, adjustable bench. Bowflex made certain that the 5.1S adjustable bench maintained the Bowflex commitment to quality and diversity.

Another important consideration was the Bowflex trademark of saving space with their machines. The company idea behind many of their models is both convenience and usability in a single piece of exercise equipment. With that in mind, Bowflex made the 5.1S strong, but it can also be stored away using minimal space.

Is the Bowflex 5.1S Adjustable Bench for You?
If you exercise at home, you have either owned a bench or wished you did. However, most traditional benches are bulky and difficult to store. Owning a bench is great, but where do you put it when you're not using it?

They make a useful, but rather cumbersome addition to your exercise room. Most traditional benches are flat. They might incline, but few offer multiple positions. If you want to add more than 100 unique exercises to your workout, a Bowflex 5.1S should be on your wish list.

What Can You Do, Using a Bowflex 5.1S Adjustable Bench?

Adding a weight bench to your fitness equipment will tremendously add to the number and type of exercises you can perform. Not only can you do various chest press moves, you'll be able to do core and balance enhancements.

Of course, the solution could be accomplished with any traditional bench. However, unlike the Bowflex 5.1S, you're going to need to address storage. In addition, the majority of these standard benches do not offer the same degree of diversity.

A bench is also less efficient if it will not handle you and all the weight you might be able to use in an exercise. The Bowflex 5.1S is built sturdy enough to support 600 pounds total. This includes your body weight and the weight of the equipment you're using.

Exercises that involve your core or require stable balance are also useful. However, if you can't get perfect balance from your bench, these exercises can be unsafe to perform. No matter what surface you use your 5.1S, it can be made level.

Bowflex made each of the four legs adjustable. This means your bench will not wobble. This stability is important for both comfort and safety. The different adjustments also increase the diversity you can add to your workouts.

Since the 5.1S will not only incline but decline, you can add dozens of inverted body exercises. Again, being tilted backwards means you must have a secure and stable bench. The adjustable versatility and perfect stability combine to make this a one-of-a-kind portable bench.

Weight benches are something you rarely use in exactly the same spot. Moving them around without any problems is important. The Bowflex 5.1S meets this need with ease. The bench itself is slightly over 5-feet in length and less than 2½-feet wide.

Wheels on the rear support bar make it fast and easy to shift the bench around the room. The wide back support adds even more support when you position the bench. The 5.1S added a set of leg supports across the front.

These allow you to perform an intense inverted abdominal exercise, plus add stability when doing decline exercises using a lot of weight. These leg cones remove in a snap if they are in the way of a particular exercise.


  • Adjustable – Being able to perform flat exercises is great, but also limits your workout routine. Even a bench that only inclines has its limitations. The Bowflex 5.1S not only allows you to perform prone and seated exercises, but it also declines.
  • Comfortable – The Bowflex 5.1S will not wobble or shake. There is an extra-wide backrest to handle different types and sizes of bodies. You can be confident in the ability to safely and comfortably perform even the most intense exercise moves.
  • Space Saving – The first advantage of the Bowflex 5.1S over traditional benches is that it stores conveniently. The 5.1S folds up flat to slide easily into a closet or a corner of your exercise room.
  • Level – Bowflex appreciates how an unlevel bench can be a problem. Since every floor may not be perfect, the 5.1S has individual leveling knobs on all four legs. No matter what floor you put it on, you can get this bench perfectly level.
  • Durable – Once you find the perfect bench, you don't want to replace it unnecessarily. The Bowflex 5.1S is sturdy and durable. To prove that point, Bowflex backs up their quality guarantee with a 15-year warranty.
  • Disadvantages

  • Backrest Gap Width – There are a few negative comments from users about the wide gap between the seat and the seat. The distance is necessary for inclining the bench and works well in these positions. However, it is wider than the gap on a standard bench when flat or declined.
  • Price – You must consider the versatility the Bowflex 5.1S provides when you determine if the cost is appealing. The bench does cost more than traditional benches, but it makes up for the difference when considering how versatile and storable it is.
  • ​Final Thoughts

    Bowflex 5.1S Stowable Bench

    If you're looking to add a weight bench to your exercise equipment, you need to give strong consideration to the Bowflex 5.1S Adjustable Bench. It offers a level of versatility far above what you might envision from a traditional bench.

    When considering the diversity of exercises and ease of storage, it is a bench in a class all by itself. You not only get a comfortable, sturdy bench, but you'll add a piece of equipment backed by an excellent 15-year warranty. If you want a complete bench, this is the one for you.
