What people are saying about the ISO-FLO

(21 customer reviews)

Iso-Flo is great and very effective on it’s own and or in conjunction with other exercise routines that include Bullworker Classic and or Streel Bow.

Highly recommended.



Chris Bowman

I like Iso Flo very much, the quality is very good and it will last a long time. The additional Iso Bow is also great.

I am glad I bought it and am always happy to train with it.


Stephen Engler

“My first workout today made me a believer in the Iso Flo’s true potential.

I could feel the burn, engaging my whole body. Not to mention the great cardio effect. AND you don’t need a door anchor to do exercises, you are the anchor….talk about portability!”

    I’m a big–a humongous–fan of the Bullworker, all the more so because it can be used virtually anywhere. I don’t care that it’s not going to make me the next Schwarzenegger or Ferrigno. At my age, 69, I don’t aspire to be (and tbh, never really did). I’m simply looking to enhance my fitness and my quality of life as best as I can for as long as I can, and I sincerely believe my work with the Bullworkers I have–the X5, the Bow Classic, and the Steel Bow–are helping me do just that.

    Good product

  3. John Abisch

    Portable, affordable, effective. Great for those who travel and want a good workout in a hotel room. Another great product from Bullworker.

  4. Duke D

    I found the Iso Flo pack to be very useful to take to work and get some exercise in. Very portable self resistance system. The durable straps & carabinar make it very versatile to be used as a bullworker extension or attached to anchoring points for other strap system training.

  5. Robert Williams

    I have been using the IsoFlo for a few months now. It is good for isometric and isotonic workouts. It’s a really flexible piece of equipment that can be used creatively. It comes with the Isobow included that I like to work my chest with.
    It’s great for taking into work with me so I can squeeze in a workout, it’s very portable and had a good quality carry bag.
    I find it works my back, arms and shoulders really well. My wife uses it for her legs and core.
    It’s my favourite piece of equipment. Feel the burn!

  6. Bruce Uhalley (verified owner)

    Excellent addition to using both the Steel Bow and the Bow Classic from Bullworker. Replacing certain exercises with the Iso-Flo makes the intensity of the exercise higher, I find. I highly recommend this Iso-Flo with the two Bullworker products I indicated for a full workout experience. I am over the age of 60 years and these products help the joints tremendously due to the years of training at the gym.

  7. rajendar menen (verified owner)

    Excellent full body workout. No complaints.

  8. Robert (verified owner)

    The Iso-Flo is my latest purchase direct from the Bullworker website. Like the other products I have ordered from them; the Iso-Flo is well made and is a great and easily portable piece of equipment. It continues where the great Iso-Bow left off; using isometric principles to build muscle. I am 71 years old and have the feeling that this, and my other Bullworker products will help me maintain my health for the years to come. Very pleased with all my purchases. Thanks!

    Ok. I’m really going against the grain. Can’t buy ISO Flo..but I do have the predecessor…the ISO Gym. The ISO gym is great and I follow the ISO Flo workouts…So I will say….my ISO gym is a bit more cumbersome but the workout are fantastic. Being able to control the effort with opposed limb..this is what the Original workout from the 1940’s ..Charles Atlas and then even Jack Lalanne did. Using your own power to do. The ISO Flo fits this bill. You control the tension with your opposing limb and effort. And the set up from movement to movement is Simple/easy & fantastic Putting this together 2x’s a week with 3 Bullworker Classic workouts each week is awesome.

    The Iso Flo … Iso-Bow on steroids!

    The IsoFlo is the IsoBow on steroids. I love the Iso-Bow. It has proven to be one of the most versatile exercise equipments delivering power, flexibility and mobility to our muscles.

    But the arrival of my Iso Flow takes that versatility several notches higher.

    My first workout today made me a believer in the Iso Flo’s true potential. It has given fresh meaning to the Bull worker Mantra ” You control the resistance, you control the results”.

    It really challenged my muscles. I could feel the burn, as my muscles pleaded for relief…not from pain but from exhaustion. I did slow deliberate reps to failure, applied Isometric holds duplicating many Zass holds then moved to constant tension of Iso Flow Isomotion engaging my whole body. Not to mention the great cardio effect.

    What also makes the Iso Flo unique is the you don’t need a door anchor to do exercises, you are the anchor….talk about portability!

    What a powerful complement to the Bullworker Line. The Iso Flow is an exercise equipment whose time has come!
