How to Choose a Treadmill for Bad Knees

Having a bad knee doesn’t cause an individual to come up with lame excuses to refrain from exercising.

Still, practically, it is evident that exercising is truly a painful affair for them.

Contrarily, the same exercise can reduce pain, provide flexibility to joints, and even improve one’s balance and stability.

There are different treadmills, each having its highlight designs and advantages.

For someone specific about reducing knee pain/joint problems by walking on a treadmill, it is ideal to choose those models that have features that can minimize stress on the knees.

Once you are given a green signal from your doctor for working out on a treadmill (doing low-impact exercises such as walking), there comes the primary problem of choosing the best treadmill for bad knees.

The main features that must never be compromised when you plan to buy a treadmill for knee pain include cushioned belt and stability.

The presence of a cushioned track helps in reducing the impact of the workout on the knees/joints by as much as 40% compared to working on hard surfaces.

For greater stability that causes no surprise impact on your joints, it is always preferred to select a model that weighs 50 pounds or more.

How to Protect Your Knee While Running on a Treadmill

Firstly, running is a high-impact activity, and secondly, running on a treadmill is different from running outside on the park/road.

If individuals don’t understand this difference and don’t take extra care to stay safe from injury, they can hurt themselves badly.

Given here are some tips to protect your knees from further pain aggravation while running on a treadmill. Posture is of utmost importance while running on a treadmill, as this helps in muscle conditioning.

Rather than forcing yourself into a specific posture, try to stay in a natural position making sure that your joints are not overextended or stressed too much.

For those of you who wonder how different is a treadmill surface compared to the ground surface, here is the answer to your lingering doubt—the treadmill surface is very flat that’s not so good for the legs and feet.

Only when there is a 3% inclination on the treadmill, it becomes as good as the outside ground surface protecting the knees and joints from injury.

Running on a treadmill with zero inclination causes pain and muscle strain for the exerciser in the knees and feet.

This is mainly because the individuals run with the knees in an extremely straight position instead of being slightly bent. In such a position, the knees cannot absorb shock properly.

It is better to use a treadmill without any motor for mimicking the same experience as running on the ground.

Also, never hold onto the bars in the front of the equipment or even the side railings as these can interrupt the balance and cause the exerciser to fall/stumble as he/she gains momentum.

Besides sticking to the right posture, also ensure that you take short and quick strides to experience minimal impact on the legs.

Never push yourself any further than what your body could handle, as this can aggravate knee injuries.

Keep an eye on any indication given by your body and act accordingly.

Above all, wear good-quality shoes that fit properly, absorb shock, and are specifically designed for running purposes.

Final Words

One is forced to use a treadmill for walking, jogging, or running when the weather is bad outside or if you cannot move out of the house due to various other reasons.

Low-impact cardio workouts benefit people with bad knees as it strengthens the muscles around the knee, increases blood flow to the cartilage, and even increases chances of weight loss, thereby reducing stress on the knees.

Running on the treadmill, especially when you suffer from bad knee problems, must be done with utmost caution.

You must consult a professional before making any decision.

Go for a model that has an optimal cushioning option, inclination levels, and speed.

Never overstrain trying to achieve better bone health as this could only lead to further damage to your knees/joints.

Before starting to work out, always get in touch with your physician and get his/her approval.
