This is crazy, I kept getting injured for 1,5 years. Thanks to this video I can finally do some isolation work for my quads, many thanks.

Just hopped on the leg extension and played around, and this is a revelation. Ron, you're a genius.

[@grantbaker7062]

I'll have to give this a try. I'll only do leg extension at the end of my leg workout, with light weight, 12-15 reps, 30 second rests. The intention is to fatigue the quads as much as possible, I'm not trying to reach concentric failure with heavy weight, but instead push my quads to the point in which I can no longer tolerate the pain and have to stop. I believe doing them with heavy weight is where you start putting too much stress on your knees, it's not an exercise meant for heavy lifting.

[@ericgale2387]

This was very helpful. For weeks when doing leg extensions I’d always feel it above my knees, this really helped

[@555sameena]

bingo , today's my legs workout, very much appreciated king Ron.

[@aliciacauthen5479]

Thank you bro, as a beginner to the gym i didnt understand why there was a huge pain in my knee as soon as i did the leg extensions, this helped me thank you!

Just finished my first proper leg day since an injury and completely hurt my right knee had to stop and switch to back day it hurt so bad. Thank you for the wisdom and God bless!

Thank you so much Ron! I have bone-on-bone osteoarthritis and am on track for two knee replacements. Part genetics, part very active life and part being fat (working on it). I so appreciate your video. My pain doc wanted me to do these youtube video where you sit in a chair. Uh no! I bought a great bench with a preacher curl/leg attachment so I can do leg extensions. and leg curls. I have a history of weight training an am very comfortable with it but was worried about leg extensions with my knees. I first have to practice extending my knees, which I can't now. I am only using the weight of the machine, adding no extra weight. Your method of moving the hip flexor forward is great! I'm not at full extension yet, but I don't feel it in my knees as much. Keep it going!

[@djmattson6491]

tks Ron ur awesome tk u i done those leg presses never had any knee pain ever and am goin to be turning 50 in 5 months tk u again u rock

[@Nailedbymiaa]

I’m so happy that I came across this video tonight. Now realizing how old it is still very relevant today.. I’d like to thank you for making this video. I’m going to try this this morning.

[@waynehammond7145]

I have found that the old fashioned leg extension machine that I used in college is best for doing leg extensions. They always had additional support under the knee joint like a roller pad. Never had any problem with knee extensions until I started using the newer style extension machines.

[@jbgood75]

Thanks for the tips! I was experiencing pain after doing reps on this machine and waking up the next day with stiff and achy knees. Thought about not using this machine anymore but now I’m going to try your tips and see how it goes.

[@charlesjackson3433]

Great video. I'm 67 my leg day is today. I'm going to focus on the points you brought up today. I've gotten a lot of very usefull information from your other videos' concerning form on diferent lifts. Thanks for sharing your knowledge and experience.

[@The.Ghost.of.Tom.Joad.]

Thanks boss. I've had knee pain from extensions for years. For the first time I know not only "why," but "how to fix it."

[@michelangelorodriguez457]

Ron Williams your content is amazing! I wish you achieve any goals you wish to achieve.

[@Cashvertising]

FANTASTIC! Such a great video. Heard this nowhere before from anyone. Look at this guy. He's a champ multiple times over, beating out many of the world's best. I'd take his advice over the generic KZbin health channel guys any day. All you ever see and hear is "don't do extensions." This one simple move, if you think about the mechanics, makes all the sense in the world. Thanks, Ron! Please keep the videos coming!

[@CaribbeanQueen72xx]

Thank u so much , I had to check on why my knee hurt so bad after this machine . Thank you so much .♥️♥️♥️🙏🏾🙏🏾🙏🏾

[@nicolaholland1]

Thanks, wish my trainer had showed me this before my knee started hurting...keeps healing with rest then gets worse going back to gym! Gladi know how to correct my form now...so simple. Thank you

[@oocc4026]

I do leg extensions and I've never experienced pain on my knees, only in the quads

[@samitambaram3873]

Very helpful in understanding why my knees started to feel the pain after doing leg extension. This video is an eye opener on where am I going wrong with the machine. Thank you

[@Grindenhausen]

Appreciate it. Went from random joint jolts of pain to a very sharp pain on my next time doing leg extensions. Quality over quantity!

[@pablosmitty4024]

Great info! I’ve def been doing them wrong and paying the price. Thanks for this!

[@marvinmay6739]

Thank you brother. I was just about to give up on leg extensions because of the pain.

[@matthewdunn566]

Thanks Mr. Williams. This is what I've been looking for. Thanks buddy

[@jrnso1749]

I couldn’t believe it 😂. That slight adjustment relived all the stress off the knees completely.

[@ss_hat]

My pain stems from the bottom of my patellar on my right knee but only after 20 mins post workout and can last for a few days. When I bend my right knee over my toes I get this aching pain on the lower half of my kneecap. I always thought it was my form from Bulgarian Split Squats as I've been doing them a good 2 months and only started feeling this pain over the past few weeks but I've since corrected my form and now it makes sense - the origin of the pain and this particular exercise. I use an incline bench and lift a single dumbbell with both legs.

[@zuleymacatherine]

This video was awesome and excellent info! Thanks!!!

[@Frkdsnbrd4103]

Thank you! I just joined the gym because I can't get big unless I use machines and I've been hearing that leg extensions are bad for the knee and I was disheartened. Thanks to you video, I learned that I've been doing it wrong because of the heavy weight but will go lighter to get the proper form.

[@SusanWilcox-h1f]

I've never heard of this before - and it's brilliant! Thank you!!

[@lizhood6132]

Thank you. I have just started again on machine exercises (moved countries, WuFlu and had to wait for my gym to be set up here) about 6 or 8 weeks ago. My outer right knee has been twinging and getting worse in that time but since I have no trouble inside the knee and walking/gym work is absolutely fine I didn't connect the two. I'm going to stop using that machine for a while and start again doing it properly when the twinging has stopped. I've always had a weakness in that knee as I was hit by a slow moving car there as a child, but no problem has ever been found. In a way, I hope it was the machine causing the pain, as otherwise it will entail doctors. Much appreciated.

[@macemace3194]

Thank you Ron! I've learned so much...things that might seem small but very significant brother! god Bless you!!

[@WootWootGuitar]

Thank you this is very helpful, Ron. I love doing leg extensions, but I have been worried about damaging my knees. Also, since I don't usually comment on videos I have to tell you I really appreciate you wearing your cross. Too many Christians are shy about their faith but you set a great example. God bless you!

I totally agree that leg extensions are bad. I've tried leg extensions specifically that day to test it a little and my knees were feeling a little beat up the next day. It's happened like 4 times and I just stopped doing it.

[@castrox1194]

Great tip I have to go over these things over and over again, techniques and tips I mean, I had this down a while back then did leg extensions recently and felt some knee discomfort because I forgot how to do them correctly and now I relearned it again. Great video.

Hello Ron I'm a big Fan from Romania i love you're videos and i like to watch every time you upload. Can i ask you if you take whey proteins supplements an witch brand if you do? And what kind of Brand do you use for Arginine? Hope you never stop uploading because i will be here watching. :D

[@markopetkovic2325]

Well done ron for these usefull videos.

[@sophies8313]

I use to love the exercsie and it was a main component in my leg days until I started experiencing knee pain. I presumed it came from squatting so stopped doing that and kept doing leg extension. It’s only recently now I’ve upped the weight on it my knees really hurt during the exercise so I think I’m gonna leave them from now

[@glennjacoby2845]

cool - I finally understand why extensions hurt my knees. Thank you! BTW, I have bone on bone arthritis and fixed it with a clean diet losing 40 pounds, running and squats and leg presses. My cartilage repaired itself.

[@warcloud500]

Been doing Leg extensions for 15 years never felt any pain and i lift light. I never go heavy.

[@exceleffects]

Interesting enough, while I was in high school, we used the leg extension to strengthen the area around the knee for basketball. It was a concentrated movement though.

[@sandracarli1110]

I've just seen a video by a German therapist saying that leg extensions are bad for the knees. Squats are good because the knees get more liquid.

[@imranmanzoor7966]

yes 100% agreed with Ron .leg extension is very bad for knees specially if you have week knees.

[@zeqwatro8573]

as always thank you Mr Williams

[@stephanM5]

When performing leg extensions shear forces on the knees are unaffected by what muscles you engage in the area of the hips. In Mr William's example the only reason you alleviate pain in the knees while performing leg extensions is due to the resistance being substantially lowered. This is a poor exercise no matter what you do with your hip flexors or what side of your mouth your tongue is located in for that matter. The only way to take pressure off of the knee joint is to drastically lower the weight or stop doing this stupid exercise altogether. Perform high rep leg presses with your feet positioned at the highest point on the pad if you want to protect your knees and grow a decent pair of quads.

[@jrippon]

John Stephan: Exactly. The load is on the front of the lower shin, so how else can the resistance be transmitted from your quads to your shins other than through the pivot at the knee.

[@AxerlexOfficial]

Sometimes I dont even know if I can trust Ron williams because sometimes his videos are truly awful...

[@jrippon]

Never come across him before but if this is anything to go by I wouldn't take him very seriously.

[@A_Kind_of_Blue]

Love your videos Ron! Great work!

[@jasonvoorhees8899]

i heard that if put some light pressure on the joints and tendons they will get more and more stronger... is that true ?

[@zupinu2000]

i guess after 3 years, we'll never know.

[@nathanielknowledge]

Thank you for an awesome explanation and demonstration!

[@djpickleballplayer]

Great tips, Ron!

[@7asuja]

What if I use resistance tube instead of the machine with loads? Surely this wouldn't hurt vastus medialis and knee joints? High and controlled reps for perfect teardrops and knee health? I mean... this feels soo freaking good!!!

[@bbrockRailFan]

Ron, I find you just gotta do higher reps. At least 10 to 15 reps. Once I get past 10 reps the weight becomes irrelevant to a point. I use to pause at the top but I dont feel that is good I like to just move the weight at a even cadence. Reps to me is even more important than the weight.
