Low-Impact Leg Lift Workout & Exercises That Protect Knees

Undeniably the leg muscles are the most critical muscles in our body for continued mobility. Besides being the largest muscles and a large contributor to our overall lean muscle mass (or lack thereof), the leg muscles also protect the knee joint.

The leg contains both the longest and the largest muscles in our body.

Outside of the spine, one of the most common ailments among our aging population is the knees.

Changing our metabolism as we change both our diet and our activity level must be addressed. The quickest way to take our metabolism to a new level is to build muscle. Science has proven that the higher the percentage of muscle mass in our body, the higher the metabolism - we burn calories faster.

Where are the largest and longest muscles in the body? In the legs. Yet, if we are fighting our weight, how do we do build these muscles outside of the swimming pool? Here are some great low impact exercises designed specifically to be low impact. Still challenging but all low impact.

Build Muscle to Protect the Knees

Building muscle to protect the knee without further injury to the knee can be problematic especially IF your knees demand a low impact exercise. This article showcases 4 great variations on the often forgotten leg lift exercise.

Muscle = Armour

An important principal which I believe should be taught alongside the ABC's is the fact that our muscles are the amour that protects our joints.

The old saying "IF you don't use it, you lose it" is truly profound when you are taking about this complicated human machine we call our body.

The old adage of RICE - Rest, Ice, Compression and Elevation is true for the first 24 hours - then after that IF you don't move it - you will actually damage your body.

It is muscle that protects our joints.

IF you are still in pain after 24 hours or IF you cannot sleep, consult a professional. Find out the correct exercises that will HELP your pain. Any further delay will harm your body. The cost is too high.

Always Always Warm-up Before Exercising - Here's Why!

We have 640 muscles in our human body. These muscles are perhaps most similar to a rubber band. A warm rubber band is very flexible. Our muscles love a warm-up because it is after a warm-up - and only after a warm-up that are muscles are flexible.

Target toning must begin only after a warm-up.

If we try to exercise without a proper warm-up, we may end up like the cold rubber band and snap the band or hurt the muscle.

The Good News - No Expensive Confusing Equipment Needed - To Protect the Knees

Home exercise can be both effective and inexpensive with the Body Bar. The Body Bar I know looks strange at first - but it works! This exercise is wonderful for the inner thigh muscles.

Journey with us as we walk through this great exercise complete with photos detailing each movement.

The Bad News - You Must Be Consistent

It will at first seem difficult. Remember everything new is difficult at first. Start slowly and do the exercises on a regular basis. It takes 21 days to change your pattern. Therefore, I always recommend starting small with a simple 2 minutes a day for you - 2Min4U. Once it becomes a habit, it really is easy! The first 21 days are critical so don't overdo it - just add your exercises into your morning routine.

Brush Our Teeth Brush Our Hair

Every single morning we brush our teeth, brush our hair, but the 640 muscles in our body are often forgotten! Change that deathly lifestyle now! Even if it is only for 2 minutes, warm-up for 1 minutes and try 1 minute of exercise. And here we will provide 4 great exercises for more beautiful legs.

Leg Lifts - One of Three Main Types of Leg Exercises

The human body is one of the most complex machines in the world. It is the only machine that can heal itself. One exercise alone will not get the job done. Beyond lunges and squats is leg lifts and within the leg lifts we have shared with you 4 great variations.

Leg Lifts Verses Lunges

The leg lifts target the inner thigh and the quadriceps. The leg lift exercise movement is different from lunges and squats. Lunges and squats are outstanding resistance exercises. However, for those of us with knee problems, these two exercises may not be a practical option.

The leg lift exercises are a great addition to any workout - and is especially loved by those with knee problems - such as myself!

Knee Problems - Seniors & Rehab Too!

For my clients who find lunges hard on the knees, the leg lifts are simple and very effective. These exercise are especially wonderful for seniors because the exercises are low impact and yet target tone the two most important skeletal muscles in the human body.

The Largest & the Longest Muscles in the Human Body

All of the exercises shown in this article work the two largest and longest muscles in the human body! No wonder these leg lifts are magical in changing your metabolism, toning and reshaping your body! Remember changing fat into muscle will 1.) protect the joints and 2.) change your metabolism thus allowing you to eat more and yet be thinner too! What are these two muscles - the longest and the largest? Read on...

The Largest Muscle in the Human Body - Quadriceps

The largest muscles in the human body are in our legs. As the diagrams to the right detail, these muscles are extensive. The king of all muscles is called the "quadricep" - and includes four muscles on the front of the thigh. This massive muscle also is connected to the largest bone in the human body - the "femur".

The Longest Muscle in the Human Body - Sartorius

The side lying leg lifts engage not only the quadriceps but also the long muscle called the sartorius.

The sartorius is the longest muscle in the human body. The sartorius as the diagram showcases runs obliquely across the thigh and descends all the way down to the knee. The name "sartorius" is derived from Latin - the word "sartorial" which means to do with tailoring. Some people have nicknamed this muscle the "tailor's muscle".

Wikipedia gives an interesting background to the etymology of the word: "There are four hypotheses as to the genesis of the name: One is that this name was chosen in reference to the cross-legged position in which tailors once sat. Another is that it refers to the location of the inferior portion of the muscle being the "inseam" or area of the inner thigh tailors commonly measure when fitting a pant. A third is that the muscle closely resembles a tailor's ribbon. Additionally, antique sewing machines required continuous cross body peddling. This combination of lateral rotation and flexion of the hip and flexion of the knee gave tailors particularly enlarged sartorius muscles."

Leg Lift Exercises Four Options Given

Four different exercises targeting the quadriceps, the sartorius and the abdominal are given as examples in this article. All leg lift exercises showcased here use either none or very minimal equipment. Yet all of these exercises deliver great results.

Leg Lifts With Equipment or Without Equipment

As you can see, the exercises we have provided here are both with added resistance equipment of the Body Bar or with simply your own body weight as shown in the videos.

Body Bar - Two Levels - Easy and Challenging - Checkout the Progression

The beauty of the leg lift with the Body Bar is this exercise offers a progression of exercises. Once you master the first movement, take it to the next level. We explain in more detail below complete with two sets of photographs.

Additionally, the Body Bar comes in different weights. I started out with the 9 lb and have worked up to the 12 lb Body Bar. Many different weights are available - I just share this with for a helpful hint.

The investment in the resistance tool is certainly worth it IF you have bad knees. Body Bar is not the only manufacturer, just an example given. Body Bar kindly supplied the needed photographs upon my request in order to fully provide the needed details of the two different types of movement. No financial consideration exists between Body Bar and the author as stated below in the FTC Disclosure and reiterated here for the sake of clarity.

Easy Leg Lifts - Side Lying Leg Lifts Variation #1A

Start with lying on your side - thus the side lying leg lift term.

Rest the Body Bar on your inner foot as shown, with the end of the bar extending no more than 1-2".

Then slowly lift your leg off the ground 6-8" as we have shown below.

You will feel both your quadricep and your sartorius contract.

Listen to your body and feel the power of the muscles in your legs.

CAUTION: If you feel your back muscles engaged - stop immediately, you need to re-position your hips.

Repeat the leg lift for 10-12 repetitions. Switch legs. Always perform the same number of repetitions on each leg unless you are fighting an injury or are in rehabilitation.

Take It Up A Level - Variation #1B

In the photos below, you will notice the Body Bar has been extended beyond the foot about 8-10". This slight change in the center of gravity dramatically changes the amount of the weight and the tension placed upon the muscles.

Follow the same steps as detailed in the Side Lying Leg Lift Variation #1A.

Recap - 4 Great Leg Exercises to Protect the Knees

As we discussed, there are three main types of exercises for building the muscle around the knee joint: squats, lunges and leg lifts. The leg lifts are the best for low impact. The leg lifts are also often the forgotten exercise or in some cases "the secret of the personal trainer".

This article details four different leg lift exercises for target toning the largest and the longest muscles in our body. Squats and lunges are great exercises, however, if you struggle with your knees hurting, try the low impact leg lift exercises just for 2 weeks. I promise a noticeable improvement.

To recap our three main points in this article:

  1. Muscle protects our joints - especially important piece of knowledge when we have sore knees.
  2. Muscle can change our metabolism. Again important piece of information when fighting the hourly challenge of the battle of the bulge.
  3. The longest and largest muscles in our legs need resistance exercise, the leg lifts provide a great workout with low impact upon the knees.

Make low impact exercises part of your daily fitness routine today!

Legs are the heart and soul of a healthy body. Not only are they the largest slow twitch muscle fiber in your body making them the best "walking" fat burner through walking... Your heart, mind and body are dependent on keeping them in good shape for oxygen enriched blood. I like the term armour, the exercise recommendation for the knee, etc., great article. Keep them coming!

@KoffeeKlath Gals,

That is the best compliment - please stick with you - I hope I motivated you enough to follow through.


You are right - it doesn't take money - it takes determination and motivation.


Great point about the slow switch muscles - completely agree. Thank you for contributing your expertise - really appreciate it.

David 470 profile image

David 470 5 years ago from Pennsylvania, United States

GmaGoldie, I have a question, since 09 my right knee makes a clicking sound when it bends. I am not sure if this was from doing squats or what, but it still does this.

My legs are VERY weak compared to my upper body. I need to do squats and stuff, but will doing them hurt my right knee more?

There is not pain it just makes a clicking sound. Not a snapping sound. Its kind of hard to explain. This may have been due to this one athletic super human that trained me on squats in march of 09....

GmaGoldie profile image

GmaGoldie 5 years ago from Madison, Wisconsin

David 470,

The best answer of course, is to seek medical attention - the medical doctor is the trained professional.

What I can do is share with you my personal observations but they are unique only to me. What I have found is the leg press machine has helped strengthen the muscles around my knees lessening my knee pain.

The leg press machine is less sexy than squats but may be safer for proper form and therefore the safety of your knees.

I have also found swimming laps with a kick board very helpful for my legs. I completely exhaust my leg muscles and use no upper body - I target only my legs. The laps with the swim board target tones my hamstrings, my sartorius and of course my quadricep and my vastus laterilus and vastus medialis (muscles on either side of the knee).

I would caution you to make sure you have your weight in proper form for the squats and you keep the range of motion for your knees limited to just strength training - remember you are targeting these muscles you are not seeking range of motion for the knees. A personal trainer is excellent at ensuring you have proper form both for your back and your knees.

Do partner with your doctor and ask a trained medical professional.

I purchased a 15lb body bar and was looking for some leg exercises to use it with without hurting my knees (tore the ACL in both knees). Leg lifts seem like the best solution!! Thank you for this information.

GmaGoldie 5 years ago from Madison, Wisconsin


Hip problems too do demand low impact exercises.


Excellent! You are brilliant - great investment, fantastic fitness tool. I know the body bar looks useless but IF you see the movements you can learn. If you try it - you can really feel the muscles activated. Remember the muscles are what protect the joints.

As a personal trainer the number one item I am ask is about the knees. I believe knees now surpass the back for frailties that we must fight and yet we are not taught the muscles protect the joints - the leg muscles are the armor of our body.

Deborah Brooks,

So many people are like you - the legs are hard to exercise and yet they are so vital.

I sincerely hope you try these out. The muscles in our legs help not just with our mobility but with our metabolism. The longest and largest muscles reside in the legs. To keep trim, in some manner, we must exercise our legs along with cardio.

I needed an inner thigh workout because my thighs touch...I don't like that and I want to do something about knee problems and I don't want to create any. You make them look so effortless...I'm adding the circle method lying on your back and down on all fours to my exercise regimen. I'm expecting get results. Thank you.

You bring up a good point. When we are fit, for a female, we should be able to see three curves with open space in our legs - by our ankles, just below our knees and yes our thighs. Our thighs should not touch.

I was working long hours and not exercising and my thighs were touching - oh, my goodness. Getting back in shape and understanding the tell tale signs of when you are in shape is critical for our health.

Very good point. Thank you so much for stopping by.

All too often we hear the word "can't" and in reality we just have to take a step. There is an old Chinese saying “It is better to take many small steps in the right direction than to make a great leap forward only to stumble backward.” - exercise takes baby steps to get started. I love these exercises because anyone and everyone can benefit.

My best friend has always had fantastic calves. For decades, I assumed it was her ballet training when in fact, I learned the other day, she does calf raises every time she brushes her teeth!

I find it fascinating how each of us is so different, all striving to improve but all with different weaknesses and strengths.

Pamela Kinnaird W,

Those body weight bars are hard to notice and then when you do, the light bulb goes off and you see its use with the legs and hips and understand how this simple weight bar can help.

It is sad how often we equate therapy to exercise when exercise is truly the best prescription for health.

The two minutes is a great way to engage our muscles and start listening to our body. Like our children, and ourselves, our body does wish to speak to us. Taking time each day is critical to our health.

We have made advancement in brushing our teeth daily, I hope we make the same advancement in exercise. Thank you for voting this up and sharing.
