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!”

    You can use these for a separate workout or attach them to your steel bow to enhance those workouts. They’re awesome for stretching too.

    The ISO FLOW was a great addition to my bull worker. It allowed me to do curls, 1 and 2 handed, standing and seated. YES!!! It helped with providing a great extension. Bullworker just became my go to equipment at home!!!

    I love my Iso-Flo. It works better than the Iso-Gym due to the fact it is more sturdy.

  7. Glenn Lefkof (verified owner)

    I have used the ISO Flow for a while now, and it’s a great, and simple apparatus that tones and strengthens your body. One half is for your feet, either pressing each side of the foot straps down on the floor or being held by your feet if you’re on your back, and the other side is for your arms to pull or push in on the handles. The strap material is just a slick, strong, flat material that slides through the same metal loop for the foot section, and is grasped by the handles. Both sides can be adjusted for length. So when I’m doing the standing exercises like arm curls or press ups ten reps of each, the arms start to burn! You wouldn’t think that you would get such a nice burn in the arms, but you do. It pumps your muscles up! And you can change the direction of your arm movements to work different muscles. Then you can lie down on your back and with your feet positioned through the foot holders and adjusting the length, you can pump your legs forward and backward one at a time giving your legs a workout. If you’re adventurous you can pump your arms and legs at the same time. You can do arm curls in this position as well with the added bonus of balance and ab strengthening. It’s a great product. It’s simple, but brilliant in concept. I find that I have to make about three adjustments to the strap lengths in the upper side for a complete workout. It’s actually fun to do this workout. The adjustments take about 30 secondes or less. All the Bullworker products are exceptional. The Iso-Bow is another unique product. And of course the Bullworker is great. They say that the strap material won’t wear out. That remains to be seen. I’m sure they have tested it as it wouldn’t be difficult to test for thousands of cycles over the same area or 100 thousand cycles rubbing back and forth over the same area.. And they say that it doesn’t wear out. If I do 100 thousand cycles with this product, then the product is worth every penny because it will take many years to get that many. 50 cycles over the same spot a day is 350 per week, 1400 per month. 16800 per year. But so far I see no wear or tear in the strap material. But it’s only been a few weeks. Overall, the Iso-Flow is terrific!
