REACH YOUR GOALS WITH BULLWORKER

As a physician and someone who is riddled with injuries from a lifetime of sports, I highly recommend the Bullworker products. With the Bow Classic and ISO-FLO, I am able to get a full body workout with no pain. I can easily modify tension to reduce stress on my shoulders and elbows, without having to compromise form or effectiveness. I am able to feel a great pump without having to pay for it that night and the next day. If you are a fan of using TRX Bands, you will love the ISO-FLO, as you can perform the same exercises you would do with TRX, but without the long and cumbersome straps and without needing a tall anchor point. Also, as someone who has been in physical therapy many times, the Bullworker products are perfect for translating my in-clinic exercises for in-home use. Overall, I couldn’t be happier as a Bullworker customer.

As a naturopathic doctor working in palliative care, I’m always searching for accessible, effective exercise equipment that meets my patients where they are—often seated or with limited mobility. The Steel Bow and X5 Pro from Bullworker are exactly what I’ve been looking for. It’s compact, portable, and adaptable, making it ideal for patients who are looking to gradually rebuild muscle strength, stability, flexibility, and mobility at their own pace. I highly recommend Bullworker products, especially for individuals going through cancer treatment or recovering from cancer.

Since the first time I tried Bullworker, I loved the variety of the full-body workouts that can be done with the bow. It is truly a high-quality fitness tool for a full-body workout. Its lightweight and compact size makes it so easy to take with me in my gym bag or my suitcase wherever I go. The customer service is outstanding, always kind and prompt responses, and the resources like the workouts found on the website make it so easy to follow, this makes me accountable for never missing a workout no matter where I may be. I love my bullworker fitness daily routine!
