Tennis elbow is a common afflication amongst tennis and golf players, but any person practicing an activity involving wrist and arm motions can also be affected.

Tennis and golfer’s elbow occur when too much stress is applied on the tendons attaching muscles to bones. If you are or have been affected by a tennis elbow injury, then you know how hard it is to get rid of it!

Luckily, there is a tool that can help recover from this injury. The Theraband FlexBar is a portable, efficient and affordable product designed to help with the recovery.

Resistance levels

Theraband FlexBar offers 4 different resistance levels. The tools are colour coded, from the lightest option to the heaviest: Yellow, Red, Green and Blue.


Light resistance flexbar

Yellow (Extra light resistance)

This is the lightest resistance level. It is mainly used by users who have a high degree of elbow pain or with a smaller body build/structure. This level requires the least amount of effort to bend the FlexBar® to a U shape (only 2.72 Kgs of force needed) and it also has the smallest diameter.

Get the yellow if you are:

  •  Suffering for a very severe injury.
  •  A woman/kid with a small body structure.

Red (Light resistance)

The next resistance level in FlexBar comes in red and it takes a bit more force to bend to a U shape (4.53 Kgs. of force needed). This resistance level is the typical starting point for women with regular built.

We recommend buying this light resistance Flexbar if you are:

  •  A lighter built man with a severe injury.
  •  If you’re a regular built woman.


Green (Medium resistance)

The following resistance level is pretty challenging for some, it takes 6.8 Kgs. of force to bend the resistance bar to a U shape and it’s considered the typical starting point for men.
You should get the green resistance level if you’re a man looking to treat Tennis elbow or Golfer’s elbow or just wanting to strengthen your grip and your forearm muscles.

We highly recommend this resistance level if you are:

  •  A man with a regular body structure.

Blue (Heavy resistance)

Heavy resistance flaxbar

This is by far the heaviest resistance level in a Flexbar; it takes 11.30 kgs. of force to bend the bar to a U shape. It is challenging to train with it.

We recommend buying the blue one if you are:

  •  A man with a strong body structure.


How to use the Theraband Flexbar?

The Theraband FlexBar is a very simple tool to use once you pick the right resistance level for your case (make sure you focus on that part).

Note: Each of the following exercises is proven to work for the majority of users when following a routine of three sets of 15 repetitions daily over six weeks.


The Tyler twist exercise

The Tyler twist is the most popular exercise, it focuses on creating an excentric movement for the wrist extensors (traction + lengthening) which was shown by countless users to deliver a high level of efficiency in treating their tennis elbow.

The Reverse Tyler twist exercise

Following the success of the Tyler twist, the demand on a similar movement for people suffering from golfer’s elbow increased. PT. Tim Tyler came up with a similar movement that creates an excentric contraction of the wrist flexers and pronators.
