What people are saying about the ISO-BOW

(22 customer reviews)

“I love this piece of equipment, so simple yet extremely effective. I carry one with me everywhere I go as it just slides in my pocket. Sitting in traffic i’ll pull it out and do a few isometric exercises or a few minutes doing nothing again i’ll do some exercises. It’s a fantastic extension to the Bullworker Bow Classic too. Anyone can use this brilliant bit of kit and ideal for stretches when feeling a bit achy.”

Trevor Hall

“I’m a huge fan of the ISO-BOW. I use this everyday, mostly for stretching while at my desk, but even before workouts it’s a great way to get deeper stretches (especially if you are not very flexible, like me!) No brainer buy for something that will last a long time and contribute to minimizing injury as I age.”

Nadim T

“Every morning starts with a bend and stretch using the ISO Bow. I start easy and then build up to very focused strong tension while breathing in and out. Excellent wake up routine.”

    My Isobowsarrived today a calendar month to the day since I ordered them. Noy Bullworker’s fault but that of the shipper. Not.impressed.
    Howvwr I am impressed with the resullt I have achieved with the original bow i have been using for the past frw months. Hope to build on that with the new bows. At age 81 I am not expecting big musele gain bur I have noticed more definition and overall fitnees from using thw bow 40 minutes a dayb5 days a week.
    Completed this week doing 100 reps of the exercises on the wall chart that came with the prigobal bow.
    The only criticism is that the exercise book that came with the new boys is too smaal. At 81 my eyesight is not what it was and the instructions are hard to read.
    Also I read of a 70 day Isobow challenge. Where can I find that.

    I run about 80 miles a week on my rebounder/mini trampoline (169,000 steps). I love the Bullworker ISO Bow. I use the ISO Bow while I am jumping/running on the rebounder. I think you get 4 times more results using it on the rebounder and bullworker at the same time.. I wanted an upper body work out while working out. The G force gives you much better results. .

    Good, solid product. Nice isometric exercise tool.

    I love the iso bow!! I’m now much more flexible than I used to be in my glory days as a high school wrestler. I’m not a contortionist by any means, but at 31, my muscle gain came with reduced flexibility. Thanks to using these iso bows, I now am able to touch my toes and stretch my hamstrings before a workout and I’m trying to really stretch my leg up to my head while bending. These combined with weightlifting, cardio and the Bow Classic keep me limber, fit and strong. Thanks a billion, Bullworker!!!

    The new version of the Iso Bow is great and a step up from the original IMO. The new grips feel much more solid and substantial. Iso Bow has been an amazing home fitness tool especially while social distancing at home. I can use it for deep stretches or to engage specific muscles or groups with a variety of isometric exercises. The included booklet is full of information and routines and is made of high quality material. Highly recommended!

    I trained as a Power Lifter for 25 years! Recent Hip surgery’s set my training way back. I read everything I could on Isometric training. My first purchase was the ISO BOW. Used properly Isometric training has gotten me back working out. If I had one one piece of equipment If would he the AMAZING Iso Bow! Best Thing I have ever purchased!

  7. Dick Herbert

    Worked out great with Contravirus. Gym out totally…Bullworker in. Feeling better already.

  8. W. Durhm

    Isobow works great! You can do everything the much higher-priced isokenator does! All at a fraction of the cost….

    Very portable, stows away in a travel bag! Feel much stronger after only 3 months ov every other day use.

    Only con is that the foam grip handles on mine disentegrated into a fine powdery mess within the first month….


    While I was training with the Bullworker, I found Chrisman Hughes to be a great source of help! He always responded to my inquires professionally and compassionally. I was improving strength and flexibility and weight loss as well, which were my main objectives. In my opinion, this company and these products are a good investment in yourself!
