    • CastleFlexx for the Win!
Size: Large 5'9 - 6'2 Color: Dark Blue
I’m genuinely impressed with the CastleFlexx Luxury mobility device—this is by far one of the most innovative tools I’ve added to my recovery and flexibility routine. The patented design combines a unique “foot hammock” with a sturdy weighted bar that makes stretching deeper and more effective than traditional straps ever did. It’s comfortable to grip and easy to set up, and I’ve found it especially helpful for loosening tight calves, hamstrings, and even lower-back tension. What sets the Luxury edition apart are the premium eco-friendly cork handles and the removable FlexxBar weight, which not only aids in stretching but also adds full-body strengthening potential. It feels both durable and well-made, giving confidence that it will hold up over time. Whether you’re getting ahead of stiffness after workouts or just trying to stay limber day-to-day, CastleFlexx makes mobility training feel effective and accessible. Highly recommended for anyone serious about flexibility and recovery! ... show more

    • My hamstrings thank you

Review Image by Ben F Ben F
I was very skeptical going in, especially given the high price point. I fully expected to take advantage of the trial period and return it, assuming I'd be disappointed. However, as someone who works in the physical therapy field, the added dorsiflexion for stretching got my interest, and I was curious enough to give it a try. While it’s true that many of these stretches can be replicated with proper movement, straps, and other tools, this product stood out to me in two key ways. First, the stretching experience itself, particularly for the hamstrings and calves, feels fantastic. The added dorsiflexion makes nerve gliding exercises significantly easier, requiring less active movement. I’ve also noticed that upper extremity stretches feel more effective, as the design provides greater leverage to really target and lengthen tissues. Second, and most importantly for me, is how effortless it feels to use. I’m someone who tries to stay limber but doesn't always feel like doing a full routine. With this device, I can get deep, passive stretches with minimal effort, even while watching TV. The best kind of stretching is the kind you can stay consistent with, and this tool has made it easier for me to work on my mobility regularly and see better results. The design and materials are top-notch, sturdy, well-constructed, and built to last, even under heavy resistance. Yes, it’s pricey, but it’s also made by a small, USA-based business, and quality labor doesn’t come cheap. With all that considered, I’m happy to say I’m keeping it and will be recommending it to others when appropriate. ... show more

    • Great high quality product
Review Image by Melissa Melissa
I’m going to give this a proper review and address the Good, Bad and Surprises using CastleFlexx. I’ve seen their ads but wasn’t convinced to buy until I saw it being used by real athletes for recovery including the Ronald Acuna Jr. and Harrison Bader – these guys can afford the best and have chosen this as one of their key fitness devices. And given the Amazon return policy, nothing to lose. Let’s start with the BAD: - It’s by far the most EXPENSIVE in its category as compared to the alternatives (inexpensive ropes/bands or even a towel I suspect) - You can’t take it on an airplane because it’s a real 2lb solid bar - Handles are natural premium cork but delicate and not ideal for taking to the gym or if you travel a lot The GOOD: - It actually WORKS to provide the most complete stretch with little effort - You don’t even need to use your hands to stretch with it - wedge it into your biceps on both arms and just relax into various stretches - Great for upper body stretching which has been difficult for me in the past given lack of flexibility - It’s made in an ethical way without plastic and the device is robust – will outlast multiple purchases of cheap ropes/bands The SURPRISES: - The Flexxbar - as they call it - has a removable 2lb weight for full body strengthening and stretch assistance – it may seem light but when you are lying down it feels like someone is helping you stretch - The Flexx Lab – provides solid guidance on how to use the product with new content added regularly (better deal than going to a stretch boutique, chiro, etc.) The VERDICT: - This has been a game changer for my flexibility, no more pain getting up in the morning or exercising and has improved my golf/tennis game and will let me get back into martial arts (where flexibility is critical) - Easy to use and portable - it goes with me everywhere and I use it while sitting at my desk throughout the day between calls - Just getting started with the flexx lab which is top notch - Already down to a cost of mere dollars per use BOTTOM LINE: If you’re strapped for cash and don’t have major pain issues with your back, hip, leg or plantar fasciitis then a regular strap should do or even towel. However, if you can get comfortable with the price (realizing that you will probably spend the same amount buying multiple ropes, bands, etc.) this is the stretch tool to buy which will last forever. ... show more
