Overview
Vive's Flex Therapy Bars are a set of three nesting TPR rods that combine to create five resistance levels, used for rehab exercises targeting the wrist, forearm and elbow.
The idea is simple: two thinner bars slide inside a thicker hollow one, so mixing and matching gives more resistance options than buying single fixed bars separately. Several reviewers used the set specifically for tennis elbow or golfer's elbow recovery, often following a physical therapist's program. The one recurring quirk is that the inner bars must be removed in a specific direction or they jam.
- Three nesting TPR bars combine for 5 resistance levels
- 12 inch length for portability and storage
- Ridged nonslip grip surface
- 60 day guarantee from Vive
Who it's for
People doing wrist, forearm or elbow rehab for tennis elbow, golfer's elbow or general grip weakness, especially those wanting a range of resistance without buying several separate bars. Not aimed at general strength training beyond rehab level loads.
What buyers say
From Amazon customer reviews.
Buyers who used the bars for tennis elbow or golfer's elbow rehab reported real relief and appreciated getting several resistance levels for close to the price of a single bar elsewhere. The main complaint is that the nested inner bars must be removed in one direction only or they jam, and a couple of reviewers felt the resistance jumped too much between the softest and fully combined settings, with one calling the material likely to get brittle over time.
Strengths and trade-offs
Drawn from this product's published specifications.
- Five resistance levels from three bars
- Lower price than buying single flex bars
- Ridged surface keeps grip secure
- Compact 12 inch size travels easily
- Inner bars must be removed in one direction only
- Bar diameters are not perfectly uniform
- Not weighted, despite some buyers expecting it
- Resistance gap between levels can feel large
Performance notes
Combining the three 12 inch TPR bars in different arrangements produces five distinct resistance levels, letting users progress as grip and forearm strength improve. The ridged surface is meant to keep grip secure during twisting and bending motions used in rehab routines. A couple of reviewers found the softest bar too easy and the fully combined bar too stiff, with less in between than they wanted.

Questions about the Vive RHB2088BLU
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How does the Vive Flex Therapy Bar 3 pack create different resistance levels?
The thick outer bar is hollow and the two thinner bars slide inside it, so combining them in different ways produces five total resistance levels.
What conditions are these therapy bars used for?
Reviewers used them for tennis elbow, golfer's elbow and general wrist and forearm rehab, often as part of a physical therapy program.
Is there a trick to removing the inner bars?
Yes, reviewers note the inner bars need to be pulled out in one specific direction; going the other way can cause them to stick.
