Description

CastleFlexx is a leading recovery device on the market, no device is more effective. - Dr. Rachael Skolnick D.C | Julliard School NYC

CastleFlexx is a patented mobility tool designed for controlled full body stretching and improved range of motion.

It helps you target common tight areas like the calves, hamstrings, hips, and lower back - For lower body your foot is cradled in our foot hammock which allows your toes to pull back evenly activating your  posterior chain.

The foot hammock promotes even foot positioning and enables deep stretches without the constant pulling and grip strain many people experience with straps.

Trusted by athletes and mobility professionals, CastleFlexx offers a pro-grade experience in a compact and durable design.

The Sport Edition is lighter than the Luxury version because it does not have the removable weight system (FlexBar) which provides stretch assistance and allows for strengthening routines. The Sport Edition features super-grip silicone handles, making it easy to carry and use outdoors, in the gym, or on the go. Made with silicone tactical grip handles.

Recommended for outdoor enthusiasts, competitive athletes, and those on a tighter budget.

HSA/FSA: May be eligible - checkout as a guest and select the TrueMed payment option. Eligibility depends on your plan.

Silicone allergy or sensitivity? Get the Luxury Edition instead.

  • CastleFlexx has been used by customers worldwide since launching in 2021.
  • Designed for repeat use at home.

Why Choose CastleFlexx Sport?

Smaller Sizes Available
CastleFlexx Sport is also available in smaller sizes for users under 5 ft.
Lightweight Design
The Sport version is 2x lighter than the Luxury version, making it more convenient for active, on-the-go use.
FlexxBar Feature
Unlike the Luxury version, the Sport does not include a removable weight. The Luxury version's weight aids in stretch assistance and full-body strengthening, simulating an external force for a deeper stretch. The Sport edition, therefore, requires more effort in arm work during stretching exercises.
Optimal Stretching Capabilities
Both versions are expertly designed to achieve optimal toe dorsiflexion and upper body stretching, ensuring a comprehensive stretching experience.
Patented and Unique
Both the Sport and Luxury versions hold USPTO patents, affirming their uniqueness and innovation in the world of stretching and flexibility tools.

How is this better than typical stretch straps?

I have limited hand strength; will this work better for me than a stretch band?

Ok, I get that, so can't I just use a towel?

    I LOVE IT! I’ve told anyone and everyone about Castle flex. In 5 days I went from being in chronic pain for 8+ months to being able to walk up stairs with no pain. Sleep better and over all better feeling. My best friend bought one as soon as I showed her how good I felt and I’ve sent the link to my Bible study group and my close friend group. I’m now going to buy one for my husband for Fathers Day.
