Slant Board: Effective Treatment for Patellar Tendonitis


Every once in a while, innovation within the fitness industry means new tools come to the mainstream, which offers newfound ways to strengthen and rehabilitate your body – the slant board is one of these.

In a world of high-tech advanced fitness equipment, it is often the simplest, most basic looking pieces of equipment which have the power to change your body for the better.

So what exactly is a slant board?

A slant board is a flat, non-slip platform designed from wood or steel, which, as the name indicates, can be changed to different levels of incline to achieve alternate levels of ‘slant’. The RPM Power slant board offers the user 5 adjustable incline levels to choose from, with each level being suited to various needs and type of stretch of exercise required.


A slant board can be used for a variety of deep stretches, which will focus on isolating muscles and tendons in your feet, glutes and legs, which help maintain overall strength and fitness. Simple to use and hard to master, deep stretching is only one of the many benefits slant boards offer, with one of the main reasons for slant boards’ popularity being their ability to fix and rehabilitate knee pain (patellar tendonitis).

Some of the benefits of training with a Slant Board include:


A slant board is the perfect tool to use when it comes to improving your balance skill in relation to its exercises. A slant board will require a static position in relation to high-energy, motion based exercises which are applicable to sports training. Being able to hold a fixed position is crucial to every day and explosive movement required by almost everyone. A slant board will force you to maintain proper posture when stretching and can assist in the strengthening of your hips, calfs, hamstrings and more.


Using a slant board for even a short amount of time daily will allow you to focus on a wide range of muscles from the hips down. This makes using a slant board the perfect tool for a warm-up or cool-down for athletes or amateurs who can’t find the time to stretch normally. The applications of using a slant board in relation to muscle recovery are exceptional, with Young et al, (2001) concluding that Slant Board exercises are effective in aiding the recovery of many injuries.

3. Fix knee pain

Knee pain is a common issue which plagues almost every active person at some point in their life. The sharp pain you can feel in your knees when exercising is an extremely common issue which is known as ‘patellar tendonitis’. The patellar tendon is a short but wide tendon which runs from your kneecap to the top of your kneecap, which absorbs a huge amount of loading in sports where explosive and sustained movement is required.

Such pains are typically caused by common issues, such as:

  • Weak thigh muscles
  • Poor hamstring and quadriceps flexibility
  • Poor explosive leg strength


When designing our slant board, we took into consideration all the other models currently being sold on the marketplace to create one which would trump all others.

Designed with premium stainless steel, the RPM Power Slant Board is built from solid stainless steel with a textured surface for optimum grip. The curved raised base heel support at the base, ensures added support and comfort while exercising/stretching even when used at the highest incline settings.

With 5 incline levels to choose from, the Slant Board acts as a squat wedge will help you diversify your workout, helping you grow stronger and gain greater mobility & flexibility in a host of exercises including squats, deadlift, tap downs and more!

Regardless of your age, level or ability, the RPM Power Slant Board is a tool which can bring a multitude of benefits to any user. Click the image to the right of this paragraph or see more information here.
